[FR] SSL options in ENV variable

[raymond-xu-gtg]

Can we add support in the WHODB_MYSQL environment variable for

• SSL mode
• SSL CA cert
• SSL client cert
• SSL client key
  in order to use SSL enabled connection? This is required for Google Cloud IAM Authentication.

Ref. https://cloud.google.com/sql/docs/mysql/iam-authentication#compare-db-auth-options

Example:

[{"host": "10.1.2.3", "user", "ray.xu", "ssl-mode": "REQUIRED", "ssl-ca": "/tmp/ca.pem", ...}]

Thank you for issues! We are testing changes on this PR: #196.

We are setting up the IAM authentication for an instance Google Cloud to test. Getting back on this thread!
