login.gov first time workflow notify-api-1250

[terrazoon]

Description

The new "Set Up Your Profile" workflow for first time users involves them being redirected to the login.gov website after they click "Join Service" in the invitation email.

TODO (optional)

• Don't merge this until the matching 1250 PR in admin is merged.
• Eventually the "password" column should go away in the users table. For right now, new users will be getting a UUID automatically for their password (once login.gov is mandatory, they will never have a need for one)

Security Considerations

Looks good to me. I just have questions about passwords/login. Will dev work flow through the login.gov sign in? If not, would we still need the password column for devs?

Dev flow is going to have to change. We will have to run the "create test user" command in order to create the first user in a clean setup. After that, we will have to log in with login.gov whether we use the sign in page, or respond to an invite.

The code LGTM.
