Add cmdline ssl options for mysql

Currently, only postgres connections support ssl options on the cmdline. Add support for specifying mysql ssl connection options on the cmdline too. 
For example:
```
--mysql_config_sslcert
--mysql_config_sslkey
--mysql_config_sslrootcert
--mysql_config_sslcapath
--mysql_config_sslcipher
--mysql_config_verify_server_cert
```
