feat(remote_command): allow empty writes to be queried/enabled/disabled by
remote command (#2153)
Support querying/enabling/disabling empty writes on one, multiple or all
replica servers
by just one remote command conveniently.
For example, after a table is migrated from a cluster A to another cluster
B by duplication,
we want to check whether that migration has been finished by decree.
However, since
empty writes would increase the decree, it is necessary to use only one
command to
disable empty writes on all replica servers of cluster A without need to
restart all of them.
