(POOLER-34) Ship clone request to ready time to metrics (#277)

Browse source 
* (POOLER-34) Ship clone request to ready time to metrics

Before, we were already capturing this metric but we failed to ship
it anywhere. This ships the appropriate metric as `time_to_ready_state`
Dashboards can be found in grafana.

* Add spec test to ensure metric is being shipped properly on
move_pending_vm_to_ready call.
