Can we change Sync_Priority value for a standby ?

[nijesh8]

Can we change the SYNC_PRIORITY value for a particular Synchronous standby in Stolon Keeper nodes ?
This is to choose 1 or 2 specific standbys as Failover targets, and keeping the remaining as less priority standbys.

Though we don't have a priority value, stolon-keeper command has a flag --can-be-synchronous-replica to convey whether a replica will be considered as synchronous replica or not (and there is also --can-be-master flag)
