Is your feature request related to a problem? Please describe.

Describe the solution you'd like

Upgrade the follower nodes first, and then upgrade the leader node last.

For a two-node cluster, we need to adjust the parameter rpl_semi_sync_master_timeout before upgrading from the node. Otherwise, the leader node will hang due to semi-sync.

Describe alternatives you've considered

rpl_semi_sync_master_timeout has been setted by xenon when the replica is 2, we need not set again.
