Remove unused DatabaseConfigModule and DatabaseConfigInitializer implementations

ReviewDb is gone and we no longer need to initialize the database
section in gerrit.config on init.

-[[createdb]]
-== Database Setup
-
-During the init phase of Gerrit you will need to specify which database to use.
-
-[[createdb_h2]]
-=== H2
-
-If you choose H2, Gerrit will automatically set up the embedded H2 database as
-backend so no set up or configuration is necessary.
-
-Using the embedded H2 database is the easiest way to get a Gerrit
-site up and running, making it ideal for proof of concepts or small team
-servers.  On the flip side, H2 is not the recommended option for large
-corporate installations. This is because there is no easy way to interact
-with the database while Gerrit is offline, it's not easy to backup the data,
-and it's not possible to set up H2 in a load balanced/hotswap configuration.
-
-If this option interests you, you might want to consider
-link:linux-quickstart.html[the quick guide].
-
-[[createdb_derby]]
-=== Apache Derby
-
-If Derby is selected, Gerrit will automatically set up the embedded Derby
-database as backend so no set up or configuration is necessary.
-
-Currently only support for embedded mode is added. There are two other
-deployment options for Apache Derby that can be added later:
-
-* link:http://db.apache.org/derby/papers/DerbyTut/ns_intro.html#Network+Server+Options[
-Derby Network Server (standalone mode)]
-
-* link:http://db.apache.org/derby/papers/DerbyTut/ns_intro.html#Embedded+Server[
-Embedded Server (hybrid mode)]
-
-[[createdb_postgres]]
-=== PostgreSQL
-
-This option is more complicated than the H2 option but is recommended
-for larger installations. It's the database backend with the largest userbase
-in the Gerrit community.
-
-Create a user for the web application within PostgreSQL, assign it a
-password, create a database to store the metadata, and grant the user
-full rights on the newly created database:
-
-----
-  $ createuser --username=postgres -RDIElPS gerrit
-  $ createdb --username=postgres -E UTF-8 -O gerrit reviewdb
-----
-
-Visit PostgreSQL's link:http://www.postgresql.org/docs/9.1/interactive/index.html[documentation] for further information regarding
-using PostgreSQL.
-
-[[createdb_mysql]]
-=== MySQL
-
-Requirements: MySQL version 5.1 or later.
-
-This option is also more complicated than the H2 option. Just as with
-PostgreSQL it's also recommended for larger installations.
-
-Create a user for the web application within the database, assign it a
-password, create a database, and give the newly created user full
-rights on it:
-
-----
-  mysql
-
-  CREATE USER 'gerrit'@'localhost' IDENTIFIED BY 'secret';
-  CREATE DATABASE reviewdb DEFAULT CHARACTER SET 'utf8';
-  GRANT ALL ON reviewdb.* TO 'gerrit'@'localhost';
-  FLUSH PRIVILEGES;
-----
-
-Visit MySQL's link:http://dev.mysql.com/doc/[documentation] for further
-information regarding using MySQL.
-
-[[createdb_mariadb]]
-=== MariaDB
-
-Requirements: MariaDB version 5.5 or later.
-
-Refer to MySQL section above how to create MariaDB database.
-
-Visit MariaDB's link:https://mariadb.com/kb/en/mariadb/[documentation] for further
-information regarding using MariaDB.
-
-[[createdb_oracle]]
-=== Oracle
-
-PostgreSQL or H2 is the recommended database for Gerrit Code Review.
-Oracle is supported for environments where running on an existing Oracle
-installation simplifies administrative overheads, such as database backups.
-
-Create a user for the web application within sqlplus, assign it a
-password, and grant the user full rights on the newly created database:
-
-----
-  SQL> create user gerrit identified by secret_password default tablespace users;
-  SQL> grant connect, resources to gerrit;
-----
-
-JDBC driver ojdbc6.jar must be obtained from your Oracle distribution. Gerrit
-initialization process tries to copy it from a known location:
-
-----
-/u01/app/oracle/product/11.2.0/xe/jdbc/lib/ojdbc6.jar
-----
-
-If this file can not be located at this place, then the alternative location
-can be provided.
-
-Instance name is the Oracle SID. Sample database section in
-$site_path/etc/gerrit.config:
-
-----
-[database]
-        type = oracle
-        instance = xe
-        hostname = localhost
-        username = gerrit
-        port = 1521
-----
-
-Sample database section in $site_path/etc/secure.config:
-
-----
-[database]
-        password = secret_password
-----
-
-[[createdb_maxdb]]
-=== SAP MaxDB
-
-SAP MaxDB is a supported database for running Gerrit Code Review. However it is
-recommended only for environments where you intend to run Gerrit on an existing
-MaxDB installation to reduce administrative overhead.
-
-In the MaxDB studio or using the SQLCLI command line interface create a user
-'gerrit' with the user class 'RESOURCE' and a password <secret password>. This
-will also create an associated schema on the database.
-
-To run Gerrit on MaxDB, you need to obtain the MaxDB JDBC driver. It can be
-found in your MaxDB installation at the following location:
-
-- on Windows 64bit at "C:\Program Files\sdb\MaxDB\runtime\jar\sapdbc.jar"
-- on Linux at "/opt/sdb/MaxDB/runtime/jar/sapdbc.jar"
-
-It needs to be stored in the 'lib' folder of the review site.
-
-In the following sample database section it is assumed that the database name is
-'reviewdb' and the database is installed on localhost:
-
-In $site_path/etc/gerrit.config:
-
-----
-[database]
-        type = maxdb
-        database = reviewdb
-        hostname = localhost
-        username = gerrit
-
-----
-
-In $site_path/etc/secure.config:
-
-----
-[database]
-        password = <secret password>
-----
-
-Visit SAP MaxDB's link:http://maxdb.sap.com/documentation/[documentation] for further
-information regarding using SAP MaxDB.
-
-[[createdb_db2]]
-=== DB2
-
-IBM DB2 is a supported database for running Gerrit Code Review. However it is
-recommended only for environments where you intend to run Gerrit on an existing
-DB2 installation to reduce administrative overhead.
-
-Create a system wide user for the Gerrit application, and grant the user
-full rights on the newly created database:
-
-----
-  db2 => create database gerrit
-  db2 => connect to gerrit
-  db2 => grant connect,accessctrl,dataaccess,dbadm,secadm on database to gerrit;
-----
-
-JDBC driver db2jcc4.jar and db2jcc_license_cu.jar must be obtained
-from your DB2 distribution. Gerrit initialization process tries to copy
-it from a known location:
-
-----
-/opt/ibm/db2/V10.5/java/db2jcc4.jar
-/opt/ibm/db2/V10.5/java/db2jcc_license_cu.jar
-----
-
-If these files cannot be located at this place, then an alternative location
-can be provided during init step execution.
-
-Sample database section in $site_path/etc/gerrit.config:
-
-----
-[database]
-        type = db2
-        database = gerrit
-        hostname = localhost
-        username = gerrit
-        port = 50001
-----
-
-Sample database section in $site_path/etc/secure.config:
-
-----
-[database]
-        password = secret_password
-----
-
-[[createdb_hana]]
-=== SAP HANA
-
-SAP HANA is a supported database for running Gerrit Code Review. However it is
-recommended only for environments where you intend to run Gerrit on an existing
-HANA installation to reduce administrative overhead.
-
-In the HANA studio or the SAP HANA Web-based Development Workbench create a user
-'GERRIT2' with the role 'RESTRICTED_USER_JDBC_ACCESS' and a password
-<secret password>. This will also create an associated schema on the database.
-As this user would be required to change the password upon first login you might
-want to to disable the password lifetime check by executing
-'ALTER USER GERRIT2 DISABLE PASSWORD LIFETIME'.
-
-To run Gerrit on HANA, you need to obtain the HANA JDBC driver. It can be found
-as described
-link:http://help.sap.com/saphelp_hanaplatform/helpdata/en/ff/15928cf5594d78b841fbbe649f04b4/frameset.htm[here].
-It needs to be stored in the 'lib' folder of the review site.
-
-In the following sample database section it is assumed that HANA is running on
-the host 'hana.host' and listening on port '4242' where a schema/user GERRIT2
-was created:
-
-In $site_path/etc/gerrit.config:
-
-----
-[database]
-        type = hana
-        hostname = hana.host
-        port = 4242
-        username = GERRIT2
-
-----
-
-In order to configure a specific database in a multi-database environment (MDC)
-the database name has to be specified additionally:
-
-In $site_path/etc/gerrit.config:
-
-----
-[database]
-        type = hana
-        hostname = hana.host
-        database = tdb1
-        port = 4242
-        username = GERRIT2
-
-----
-
-In $site_path/etc/secure.config:
-
-----
-[database]
-        password = <secret password>
-----
-
-Visit SAP HANA's link:http://help.sap.com/hana_appliance/[documentation] for
-further information regarding using SAP HANA.
