[tests] fix flakiness in catalog_manager_tsk-itest
After recent updates the catalog_manager_tsk-itest became unstable
in TSAN configuration. The failure scenario looks like the following:
* 3 masters are running with --raft_enable_pre_election=false flag
and short raft heartbeat interval.
* The test client sends CreateTable request. The server side completes
the request, but once the storm of master re-elections starts,
the client cannot get the authoritative answer on its
IsCreateTableDone requests because master leadership changes
every 40-100ms. As as result, after retrying IsCreateTableDone
request many times, the client times out on its CreateTable request.
Making the raft heartbeat interval higher helps keeping the master
leadership intervals longer, so the client has better chance of
getting authoritative response from the masters.
