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
