This migrates the afsmon script from puppet deploying on
mirror-update.openstack.org to ansible deploying on
mirror-update.opendev.org.
There is nothing particularly special and this just a straight install
with some minor dependencies. Since we have log publishing running on
the opendev.org server, we publish the update logs alongside the
others.
