efa94c5735 Fix use after free in mysqlxx::Pool::tryGet()

deleted the Connection just before the Entry went out of scope.

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

a47ffd191d 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.
