> To handle:
>  # Introduce two states of failover db property to denote nature of database at the time failover was initiated.
>  # If failover start config is enabled and dump directory contains failover marker file, then in incremental load as a preAckTask, we should
>  ## Remove repl.target.for from target db.
>  ## Set repl.failover.endpoint = "TARGET"
>  ## Updated the replication metrics saying that target cluster is failover ready
>  # In the first dump operation in reverse direction, presence of failover ready marker and repl.failover.endpoint = "TARGET" will be used as indicator for bootstrap iteration.
>  # In any dump operation except the first dump operation in reverse dxn, if repl.failover.endpoint is set for db and failover start config is set to false, then remove this property.
>  # In incremental load, if the failover start config is disabled, then add repl.target.for and remove repl.failover.endpoint if present.
