Sigh, accidentally pressed "enter" too early. Anyways...

From the version-control-tools docs: "On the SSH servers, the ``/etc/mercurial/pushdataaggregator_groups`` file lists all hgweb mirrors that must have acknowledged replication of a message before that message is re-published to ``replicatedpushdata`` Kafka topic." Essentially, once the hosts in this list have all acknowledged a message, we consider the data in the message "replicated" and expose it to the world via the "replicatedserved" repoview. However at this time, we only write the file out to the hgssh master server. This means our auto-failover write server (hgssh2) will not have access to this document in the event it comes online and takes over as the master server. We should move this file to the NFS mount, so both servers have access to it as needed.

This commit changes the canonical path of the "pushdataaggregator_groups"
file from /etc/mercurial to /repo/hg. With this change, the
file is now on the shared NFS mount and is accessible by the
ssh failover server.

I have already copied the file to the new location, so this should
"just work" once we deploy the change. Then we will just need to
delete the old file.
