Not able to connect to MySQL database using TLS

[soerenschneider]

Baikal version: 0.9.5

Expected behaviour: Connecting to a MySQL/MariaDB database that requires encrypted connections works.

Current behaviour: Connecting to MySQL database that enforces encryption doesn't work, the wizard to configure the database shows the following error.

Validation error
Baïkal was not able to establish a connexion to the MySQL database as configured.
MySQL says: SQLSTATE[HY000] [3159] Connections using insecure transport are prohibited while --require_secure_transport=ON.

Steps to reproduce:

1. Setup a MySQL database using TLS certs using secure transport
2. Spin up a fresh Baikal server and try to point it to the database
