Allow to enable/disable push/pull replication filters

The multi-site plugin had always enabled all replication filtering with
the checking of their global-refdb status. Although it is a good default
to have, the lack of flexibility brought some additional performance
issues when running unneeded checks of hundreds of thousands of refs
against the global-refdb. Example: the replication endpoint is not
Gerrit or is a Gerrit replica, therefore there is no need to integrate
and check with the global-refdb consistency, because the endpoint won't
be tracked under it anyway.

On Cloud environments where the global-refdb is provided as a service,
the consumption of the APIs is very expensive and can also be capped or
rate-limited, causing potential outages due to unneeded calls.

Introduce two new settings for enabling/disabling the filtering
individually for the push or pull-replication plugins.

Example:

[ref-database]
  pushReplicationFilterClassEnabled = false
