[Feature Request] Add TLS support

[jmkgreen]

It would be nice to have startup flags to load a key and private certificate for TLS support, to allow us to reach remote instances via https.

This exists in A1111 - uncertain if you are based on the same enabling framework. For them, --tls-keyfile and --tls-certfile work just fine.

Thanks for all your hard work!

You can probably just setup a reverse proxy with nginx or the like, there is usually no reason to implement this kind of stuff on the application side.

FWIW this supports the idea it is included in the framework but may require some parameter support when launching (which I guess is what A1111 did).
