Wojciech Mitros ab12083525 test: propagate view update backlog before partition delete ...

In the test_delete_partition_rows_from_table_with_mv case we perform
a deletion of a large partition to verify that the deletion will
self-throttle when generating many view updates.
Before the deletion, we first build the materialized view, which causes
the view update backlog to grow. The backlog should be back to empty
when the view building finishes, and we do wait for that to happen, but
the information about the backlog drop may not be propagated to the
delete coordinator in time - the gossip interval is 1s and we perform
no other writes between the nodes in the meantime, so we don't make use
of the "piggyback" mechanism of propagating view backlog either. If the
coordinator thinks that the backlog is high on the replica, it may reject
the delete, failing this test.
We change this in this patch - after the view is built, we perform an
extra write from the coordinator. When the write finishes, the coordinator
will have the up-to-date view backlog and can proceed with the DELETE.
Additionally, we enable the "update_backlog_immediately" injection, which
makes the node backlog (the highest backlog across shards) update immediately
after each change.
