Pavel Emelyanov eb3b237e05 tablet_allocator: Add initial tablets scale to config ...

When allocating tablets for table for the frist time their initial count
is calculated so that each shard in a cluster gets one tablet. It may
happen that more than one initial tablet per shard is better, e.g. perf
tests typically rely on that.

It's possible to specify the initial tablets count when creating a
keyspace, this number doesn't take the cluster topology into
consideration and may also be not very nice.

As a temporary solution (e.g. for perf tests) we may add a configurable
that scales the initial number of calculated tablets by some factor
