Support Azure AD authentication

[ptoonen]

Currently the CLI only supports authentication using integrated (windows only) and basic authentication. It would be nice if it would support authentication using modern authentication methods such as Azure AD.

I haven't done much with Azure AD so far, so I don't know what would be required here. Can you point to any documentation on how we would do this from a command line tool?

I'll pick this one up.
