Changed client to allow http

This merge requests adds a --notls flag to all subcommands of bitmaskcfg which send requests to the menshen api. The flag ensures omitting TLS for development reasons is allowed - in case the host url contains http instead of https. This allows us to test a locally running jnk, jnk-compose or a manually setup menshen API on localhost against bitmaskcfg.
