TLS certificate validation without needs to provide certificate client side

In order to have SSL connections, there was 3 solutions:

• Have server certificats generated with trusted node.js Certificate Authorities (CA) in java default truststore, like

  jdbc:mariadb://host/db?sslMode=verify-full

• Configure connector with server certificate like:

  jdbc:mariadb://host/db?sslMode=verify-full&serverSslCert=...`

• disable certificate ssl verification (not secured!) like:

  jdbc:mariadb://host/db?sslMode=trust`

Since MariaDB 11.4.1 and MDEV-31855, connector doesn't need to have server certificate anymore, permitting simple configuration like even for certificate without CA present in truststore. more info on see https://mariadb.org/mission-impossible-zero-configuration-ssl/

This permit easier client configuration but have a few limitations:

• user must use a password
• authentication use must be either mysql_native_password / client_ed25519
