Secure mqtt feature request

[lerra]

Is your feature request related to a problem? Please describe. I would like to have encrypted communication, the only thing that is holding me back from switching from esphome is the encryption part.

Describe the solution you'd like To be able to use secure mqtt, if possible with client certificates.

Describe alternatives you've considered Secure mqtt to verify the server certificate

Additional context I want all my IoT devices to use encryption even if it is locally

Hm, this should be possible to do given PubSubClient supports certificates. Ill look into it.
