There currently does not exist observability for replication lag in PCR in the DB Console. As replication lag is essentially RPO for customers, this metric should be made available to them in the dashboard. This commit adds the metric as the difference between the wall time and the reported replicated time.
Fixes #120652
Release note (ui change): Added observability for PCR replication lag to the metrics dashboard
Release justification: Add missing observability for PCR
