implement secure (https) tcp connection in adex-cli

Impact

If we want CLI to work with remote nodes, then yes it should work over HTTP

Should be HTTPS, else the rpc password is sent in cleartext over internet. There is an issue about this https://github.com/KomodoPlatform/atomicDEX-API/issues/1324 and i think it's an easy task.

Provide secure (https) connection to mm2 was confusing since we already have it implemented, so I updated the title.
