CA certificate support

[salieri]

I know that Medis supports redis-cli --cert and --key equivalent authentication with TLS.

Could you also add support for --cacert? For example GCP Memorystore Redis instances require that by default, if TLS is enabled but authentication is not.

Medis doesn't validate certificates on the client side so if authentication is not enabled, I assume only enable the SSL checkbox should do the trick?

@luin I tried that, but it does not work.

Sorry for the inconvenience! Did you connect to the Redis instance through port forwarding via a Compute Engine instance? What error did you see?
