Enable support for verify-ca SSL mode for cases when hostname verification is not possible/required #2461

What is this change about?

Bosh docs claim that bosh provides support for the director DB TLS config property skip_host_verify, but unfortunately there was not implementation in the code or support in the director specs template. This PR provides support for this property, enabling another SSL verification mode (verify-ca for postgres, verify_ca for mysql2). This will especially be useful for enabling TLS communication with GCP databases, where hostname verification is currently not possible.

What tests have you run against this PR?

Ran the director unit tests and verified the usage of a dev-release with this feature on a development environment.

How should this change be described in bosh release notes?

Provide support for verify-ca SSL mode by enabling skip_host_verify director DB TLS config.

Does this PR introduce a breaking change?

No
