Added ssl_mode flag to mysqldb
Fixes: #5692
ssl_mode flag is added to mysqldb
### Description
mysqldb driver supports "ssl_mode" flag, which can be one of following values:
"DISABLED", "PREFERRED", "REQUIRED", "VERIFY_CA", "VERIFY_IDENTITY".
Depending on these values MySQL will behave accordingly to them.
So this flag has been added to the sqlaclhemy. So in case if TLS is not supported on the server, we can drop the connection right away.
