`system stop merges` w/o table name has global effect, so the rest of the tests is affected. Also `optimize` is more suitable here so that the end result is the same every time.

Do not use SET via <full_query> in perf tests
...
Since if the connection will be closed (by some reason), then the
setting will not be applied after transparent reconnect (since only
native clickhouse-client can do this, since it parses the query, but
perf tests uses python driver).
Just use inplace SETTINGS clause or <settings>.

These ProfileEvents was ArenaAllocChunks (it shows ~1.5M events per
second), and the reason is that the table has
SimpleAggregateFunction(String) in PK, which requires Arena.
But most of the time there Arena wasn't even used, so avoid this cost by
re-creating Arena only if it was "used" (i.e. has new chunks).
Another possibility is to avoid populating Arena::head in ctor, but this
will make the Arena code more complex, so for now this was preferred.
Also as a long-term solution it worth looking at implementing them via
RCU (to move the extra overhead out from the write code path into read
side).
