Adding 'Previous Role' to the reconfiguration text

[vpavlovicMSFT]

Currently, if a partition is undergoing reconfiguration, there is no means to determine the primary replica, as the only information available to customers via SFX is the target role of the replica. The introduction of 'Previous Role' will significantly reduce the risk of accidentally terminating the primary replica, a scenario that could potentially lead to data loss.

While a partition is undergoing reconfiguration, in addition to the 'Target Role', 'Previous Role' will also be displayed.
