Azat Khuzhin 4f41ebcae3 Add settings (for connections) for MySQL storage engine
Default settings are not very efficient, since they do not even reuse
connections.
And when each query requires connection you can have only ~80 QPS, while
by simply enabling connection reuse (connection_auto_close=false) you
can have ~500 QPS (and by increasing connection_pool_size you can have
better QPS throughput).

So this patch allows to pass through some connection related settings
for the StorageMySQL engine, like:
- connection_pool_size=16
- connection_max_tries=3
- connection_auto_close=true

v2: remove connection_pool_default_size
v3: remove num_tries_on_connection_loss
