> PHOENIX-7493 introduced a new Role ActiveToStandy, in that state all the
> mutations are blocked at server side.
> It states that graceful failover is achieved by the following steps
> # Change the Active cluster’s role to ActiveToStandby,
> # Wait for the replication data is drained
> # Change the Standby cluster’s role to Active, and the ActiveToStandby
> cluster’s role Standby
> We need to handle Role Transitions of step 1. in Failover HA Policy where we
> should close all the connections for more role transitions instead of closing
> it in only ACTIVE -> STANDBY transition. For example below role transitions
> needs to handled
> ACTIVE -> ACTIVE_TO_STANDBY
