Doc/storage.md: fix mysql sample query

connector/gitlab: implement useLoginAsID as in GitHub connector

microsoft: option for group UUIDs instead of name and group whitelist

add connector_id to example app

Now, we'll return a standard error, and have the caller act upon this
being an instance of authErr.

Also changes the storage.AuthRequest return to a pointer, and returns
nil in error cases.

Add VerifyPassword to API

It takes in an email and plain text password to verify. If it fails to find a password stored for email, it returns not_found. If it finds the password hash stored but that hash doesn't match the password passed via the API, it returns verified = false, else it returns verified = true.

MAINTAINERS: remove ericchiang@

need to know why any of the code is so crazy :)
