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

MySQL dictionary source: A mechanism for retrying unexpected connection loss during communication with mysql server ( #21237 )
...
* Added a new type of Exception
for better recognition of connection failures
* Added more logging for mysql communication
* Retries on connection loss during query.
Make MySQL dictionary source resilient to unexpected loss of connection
during querying MySQL. This behavior is controlled with
".fail_on_connection_loss" config parameter, which defaults to false.
* Stripped some debugging leftover garbage
* Minor followup corrections
* Corrections after PR comments
* Yet more fixes

Change my_bool to bool.
...
The my_bool type no longer exists, and people may have been using it in their own code since some mysql.h functions have been returning that. The recommended fix is to use bool or int, which will work both in 8.0 and older versions.
