🎉Source MySQL - added option to connect using SSL

[etsybaev]

What

We want to support TLS encryption when connecting to the MySQL source.

How

Added option to connect using SSL.
Note that we do NOT support certificate verification as part of this issue -- just encryption of data over the wire. In other words, the focus is protecting against eavesdropping, not man-in-the-middle attacks.

Tested with a testcontainer. It appears that it already contains some certificates

Also checked that If SSL is disabled on DB side - then Airbyte will show an error on UI on check connection stage

Looks good! I have two minor suggestions:

1. For consistency, can MySqlSSLSourceAcceptanceTest be renamed to MySqlSslSourceAcceptanceTest.java? (SSL -> Ssl)
2. As mentioned in the comment, verifyServerCertificate=false should be included in the unit test to fully match the code.
