The current driver has no option to allow the usage of SSL connections on mysql. I've used the same name params as mysql client.
An example of mysql client usage would be:

mysql --ssl-ca='path_to_ca.pem' --ssl-cert='path_to_client_cert.pem' --ssl-key='path_to_client_key.pem'

refactor secure connection as params

remove space

add space

refactor secure connection

rename method

rename method

docs: add ssl params to use in mysqli driver

rename test method

refactor method setSecureConnection

fix bug

add comment to method

remove string escaping

fixes #2302

- marks boolean column type commented for distinction

fixes #2182

 Closes #2436

So they get passed to the SQLLogger on `Statement::execute`.

Closes #2261
Closes #2262
Closes #2386

Improve return type's phpdoc because it wasn't clear from the phpdoc or the online documentation what would happen if no row was found.

When following error message is shown, then it will get converted to the
correct Exception classs of NotNullConstraintViolationException:

  PDOException: SQLSTATE[HY000]: General error: 1364 Field '...' doesn't have a
  default value

- have forgot -> have forgotten
- larger or equal to 0 -> larger than or equal to 0

This allows a subclass to be used fluently without confusing static
analysis tools.

Without using ``--list|-l`` you get a too many arguments error.

As an example ...

```
