MongoDBStatusHandler. is_current_unit_ready( self , ignore_unhealthy_upgrade: bool )

Returns True if the current status is related to a mimsatch in revision.

Description

Note: A few functions calling this method receive states differently. One receives them by "goal state" which processes data differently and the other via the ".status" property. Hence we have to be flexible to handle each.
