CA-395174: Try to unarchive VM's metrics when they aren't running

Backport xen-api.git 71c39605b3a2dd6eddeba42a5b482b4fc1b3a4e8 Non-running VMs' metrics are stored in the coordinator. When the coordinator is asked about the metrics try to unarchive them instead of failing while trying to fetch the coordinator's IP address. This needs to force the HTTP method of the query to be POST Also returns a Service Unavailable when the host is marked as Broken.
