Is your feature request related to a problem? Please describe.

This is useful if you have a non-default realm name. At the moment, it is impossible to use the CLI as it can either not generate a token or if you generate the token externally, you cant use it because it will complain that a Polaris-Realm header is not supplied.

Describe the solution you'd like

Allow for the CLI to support custom realms
