Support custom token provider with documentation and example

[buzzware]

Why this feature is required (specific use-cases will be appreciated)?

Just as the process for providing a custom user provider is documented here https://docs.adonisjs.com/guides/auth/custom-user-provider there are many authentication servers such as Firebase Auth and IdentityServer that could be integrated with a custom token provider, but Adonis seems to only support either database or redis TokenProviders.

Have you tried any other work arounds?

Not yet

Are you willing to work on it with little guidance?

Yes

It will require some internal architecture changes. Lemme see if I can pick it up in coming days

Would this include auth0 token provider functionality? I've been banging against this and it's prevented my project from moving forward. It'd be nice to figure out if we could leverage passport to handle it somehow.
