feat(cli): add auth command (#11004)

[elasticspoon]

Fixes #11004 (partially)

Creates the command coder auth for authentication purposes.

coder auth has 3 sub-commands login, status and token. Currently the sub-commands make 2 requests to the server: validation of the user and an additional command for sub-command info (token info, etc.)

coder auth status and coder auth token commands return an error if the user is not authenticated when they are called.

$ > coder auth status
Encountered an error running "coder auth status", see "coder auth status --help" for more information
error: You are not logged in. Try logging in using 'coder login <url>'.
exit status 1

coder auth

Just returns the help message.

coder auth login

This is the same command as coder login.

coder auth status

Informs the user about their authentication status. It may make sense for this to not show an error if called when user is not logged in.

$ > coder auth status
Hello there, admin! You're authenticated at http://localhost:8080.

coder auth token

Informs the user of their token string and the expiration time of the token. (Maybe coder auth session is a better name or alias?)

$ > coder auth token
Your session token 'DqSDeIXhgx-ABpLuIJ5PnLJjtvdUwmRK5' expires at 2024-04-13 18:08:59.278587 -0400 EDT.

I noticed when the user provides --token or the env, this might lead to some confusion as to where auth status originates from. It might be good to show "source" here, i.e. either it's from config, env or flag.

Hi @elasticspoon could you address review suggestions so the PR doesn't stale and close. Thank you for the contribution. :)
