Tarun Pothulapati f05f5bd1c3 [ws-rollout] Add prometheus init check ...

When given a non-usable `--prometheus-url`, We start the
rollout without verifying if the prometheus is reachable or not. This
is a problem as we will be unable to get the metrics from prometheus
and hence the rollout will be reverted later causing unnecessary
time waste.

This can be prevented by performing a simple check to see if the
prometheus is reachable or not. `up` query is used instead of
key metrics as we can't be sure of their existence.
