The GitHub credential provider allows authentication via GitHub.
Users provide a personal access token to log in, and the credential
provider verifies they're part of the correct organization and then
maps the user to a set of Vault policies according to the teams they're
part of.
After enabling the credential provider, use the "config" route to
configure it.
