`uaa help` expects too much knowledge

I want to log in to the UAA used by my cloudfoundry to perform some basic user management.

Getting Tokens:
  get-authcode-token            Obtain an access token using the authorization_code grant type
  get-client-credentials-token  Obtain an access token using the client_credentials grant type
  get-implicit-token            Obtain an access token using the implicit grant type
  get-password-token            Obtain an access token using the password grant type
  get-token-key                 View the key for validating UAA's JWT token signatures
  get-token-keys                View all keys the UAA has used to sign JWT tokens
  refresh-token                 Obtain an access token using the refresh_token grant type

All of these descriptions expect a lot of context about UAA.

Is it possible to have a simple login flow instead, just like when I go to the UAA web interface?

Start by reviewing the uaa help command list and the existing token-related flows described in the issue. Determine how a browser-like login should fit the CLI and define the expected user interaction and completion criteria. The issue is old and names no files or tests, so repository exploration and maintainer guidance are needed before implementation.
