Roman Puchkovskiy updated IGNITE-22889:
---------------------------------------
Description: Metastorage majority may be lost forever. Without a majority,
a Raft group (and Metastorage is backed by a Raft group called MG) cannot
function. We need a way to reconfigure such a MG forcefully. We need to take
into consideration a possibility for the lost majority to return after or duing
the repair. Such a return should not cause inconsistencies and other troubles.
