Return config validation errors in one go

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.
