> 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
> ACTIVE_TO_STANDBY -> STANDBY
