Kirill Gusakov updated IGNITE-21253:
------------------------------------
Description:
*Motivation*
According to comment we need to switch zone assignments, only when all zone
tables finish their rebalances.
To implement this behaviour we need to implement the metastorage counter of
tables, which will be decreased on every successfull table rebalance.
*Definition of done*
- Counter of zone tables created on the rebalance start and decreased with
every successfull table rebalance
*Implementation notes*
- on pending update we set the counter in metastore (if it is not exist). other
tables can't be added because of "avoid table creation during the rebalance"
ticket.
- on the rebalance done instead of the current logic we decrease the counter
(with compareAndSet).
- the separate listener on every node listen to the counters and when it
decreased to 0 - do the usual logic with planned->pending, pending->stable and
etc.

we need to switch zone assignments, only when all zone tables finish their
rebalances.
To implement this behaviour we need to implement the metastorage counter of
tables, which will be decreased on every successfull table rebalance.
*Definition of done*
- Counter of zone tables created on the rebalance start and decreased with
every successfull table rebalance
> Implement a counter for number of rebalancing tables inside the zone
