Add ssh_server option to Gerrit driver

In a multi-host Gerrit environment (HA or failover) it's plausible
that admins may use one mechanism for managing ingress for HTTP
requests and a different for SSH requests.  Or admins may have
different firewall rules for each. To accomodate these situations,
Add an "ssh_server" configuration item for Gerrit.  This makes the
set of hostname-like items the following:

* server: the HTTP hostname and default for all others
* canonical_hostname: what to use for golang-style git paths
* ssh_server: the hostname to use for SSH connections
* baseurl: the base URL for HTTP connections

The following are equivalent:
  server=review.example.com
  ssh_server=ssh-review.example.com
and:
  server=ssh-review.example.com
  baseurl=https://review.example.com
