[Issue] Consider adding `azd auth status`

[jongio]

I can check auth status like this

azd auth login --check-status

It took me a while to figure that out and needed help from the team.

It would be more intuitive to have

azd auth status

Like the gh cli: https://cli.github.com/manual/gh_auth

I think this would be a nice DX and has a clean memorable command, common to other CLI status checks. cc @rajeshkamal5050
