feat(modules/redpanda): support tls

[abemedia]

What does this PR do?

Adds WithEnableTLS option to enable TLS with a custom certificate and key PEM.

I also tweaked redpanda to clean up any temporary files as it currently leaves behind a bunch of files on every run which are never removed. Happy to move that into a separate PR if you guys feel it conflates this one a little too much.

Why is it important?

This allows testing code which requires TLS connections to Kafka.
