hci login
Configure token for authentication to hercules-ci.com or Hercules CI Enterprise.
This will present a unique URL for a page where you can approve the login.
When successful, an authentication token is persisted to
credentials.json.
This token can then be used by the other hci subcommands.
Users of Hercules CI Enterprise should set the HERCULES_CI_API_BASE_URL
environment variable in their profile and/or session before logging in and
before running any other commands.
