Add interface for ListProjects REST endpoint

ListProjects is a legacy REST endpoint that was used to list/query
projects before we had a project index, but it's still widely used (e.g.
from the ls-projects SSH command or from Gerrit's web frontend to
populate the repository list). With QueryProjects we have a REST
endpoint that uses the project index for querying projects which should
be used instead, but it doesn't support all functionality of the
ListProject REST endpoint.

At Google we want to deprecate most of the options that the ListProjects
REST endpoint supports so that ListProjects can delegate all requests to
QueryProjects. Doing this is a backwards incompatible change which will
break the REST API and the SSH API for listing projects. This is an API
that is known to have lots of usage by automation tools and hence
breaking this API for everyone is not an option.

By adding an interface for ListProjects we can replace the REST endpoint
implementation internally at Google, so that this breakage only affects
Google, but no one else.

Unfortunately it's not possible to apply @Option annotations on the
interface methods. To avoid that all implementations need to define the
options by themselves we add an AbstractListProjects implementation that
defines the options and that can be extended by ListProjects
implementations.

The ListProjects interface is used everywhere where projects need to be
listed, except from the ls-projects SSH command which has special needs.
This is fine for us (Google) since we are not using SSH.

Dynamic options beans need to be bound on the ListProjects
implementation class.

Gerrit Code Review

Gerrit is a code review and project management tool for Git based projects.

Build Status Maven Central

Objective

Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.

Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.

Documentation

For information about how to install and use Gerrit, refer to the documentation.

Source

Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.

Reporting bugs

Please report bugs on the issue tracker.

Contribute

Gerrit is the work of hundreds of contributors. We appreciate your help!

Please read the contribution guidelines.

Note that we do not accept Pull Requests via the Github mirror.

Getting in contact

The Developer Mailing list is repo-discuss on Google Groups.

License

Gerrit is provided under the Apache License 2.0.

Build

Install Bazel and run the following:

    git clone --recurse-submodules https://gerrit.googlesource.com/gerrit
    cd gerrit && bazel build release

Install binary packages (Deb/Rpm)

The instruction how to configure GerritForge/BinTray repositories is here

On Debian/Ubuntu run:

    apt-get update && apt-get install gerrit=<version>-<release>

NOTE: release is a counter that starts with 1 and indicates the number of packages that have been released with the same version of the software.

On CentOS/RedHat run:

    yum clean all && yum install gerrit-<version>[-<release>]

On Fedora run:

    dnf clean all && dnf install gerrit-<version>[-<release>]

Use pre-built Gerrit images on Docker

Docker images of Gerrit are available on DockerHub

To run a CentOS 8 based Gerrit image:

    docker run -p 8080:8080 gerritcodereview/gerrit[:version]-centos8

To run a Ubuntu 20.04 based Gerrit image:

    docker run -p 8080:8080 gerritcodereview/gerrit[:version]-ubuntu20

NOTE: release is optional. Last released package of the version is installed if the release number is omitted.
