* Update plugins/replication from branch 'master'
  - Add support for direct replication to another Gerrit instance
    
    Currently when replicating to another Gerrit instance replication plugin
    requires also system SSH access in order to create, delete and update
    HEAD reference of replicated project. For those three operations plugin
    will execute system commands over SSH.
    
    When other site of replication is also a Gerrit server we can use its
    SSH API to perform operations mentioned above. Then we drop dependency
    on system SSH access.
    
    In order to set up a SSH connection between two Gerrit instances, one
    must generate ssh-key-pair with empty passphrase. Then this key-pair can
    be set to be used for connecting to explicitly configured destination
    host.
    
    TEST PLAN:
    To test this patch it is recommended to generate new ssh-key-pair and
    configure the ssh client like follows:
    
     * ssh-keygen -f ~/.ssh/empty-passphrase
     * echo "Host localhost\n\tPort 29419\n\tIdentityFile ~/.ssh/empty-passphrase" >> ~/.ssh/config
    
    Then set up a second Gerrit instance (set up sshd to listen on port
    29419) which will be the replication destination and create
    replication user with public ssh-key from ~/.ssh/empty-passphrase.pub.
    On the replication master server etc/replication.config needs to be
    adjusted as well:
    
     [remote "other-gerrit"]
         url = ssh://$replication_user@localhost:29419/${name}.git
         adminUrl = gerrit+ssh://$replication_user@localhost:29419/
    
    After starting both instances creating a project in the master will
    result in the same project created on the replication destination.
    Of course Gerrit access rights still apply, therefore $replication_user
    should have create project capability and push rights.
