Refactor cmdline parsing into gerrit-server

Now that both gerrit-sshd and gerrit-httpd use CmdLineParser, it makes
sense that the handlers for particular classes exist in a module
accessible by both.  This change moves the command line parsing portion
of SshModule into gerrit-server in a class called CmdLineParserModule.
