Improve tiger auth status output

[nathanjcochran]

This PR updates the CLI to hit the new GET /public/api/v1/auth/info endpoint, which returns information about the API key being used to access the API. This is useful for a variety of reasons:

1. tiger auth status can now hit that API endpoint to verify the validity of the API key, instead of just reporting the presence of stored credentials (which might have been revoked, or became invalid for some other reason).
2. tiger auth status now display significantly more information in its output, such as the name and public key of the credentials, the user who issued them, which project their associated with, etc. It also now supports the -o/--output flag, which controls the output format (table, json, or yaml).
3. tiger auth login now hits the endpoint to verify the validity of the credentials, instead of hitting some other random API endpoint.
4. tiger auth login also uses the endpoint to get the project ID corresponding to the public and secret keys, which removes the need for the --project-id/TIGER_PROJECT_ID parameters when using the manual credentials flow (i.e. when not using the interactive OAuth login flow).
5. tiger auth login now hits the POST /public/api/v1/analytics/identify endpoint to identify the user upon login. This associates a user ID and email address with future CLI events, making it easier to associate them with console events as well as to filter internal users out of analytics data.
