OAuth is a token based login mechanism that doesn't rely on a username and
password mapping. In order to use this login mechanism with JupyerHub the
login handlers need to be overridden. OAuthenticator overrides these handlers
for the common OAuth2 identity providers allowing them to be plugged in and
used with JupyterHub.

The following authentication services are supported through their own
authenticator: Auth0, Azure AD, Bitbucket, CILogon, FeiShu, GitHub, GitLab,
Globus, Google, MediaWiki, OpenShift.

There is also a GenericAuthenticator that can be configured with any OAuth 2.0
identity provider or can be used to create a new authenticator class when
additional customization is needed.
