authtest: to be run within backend integration test suite
Created by: unknwon
This PR adds authtest suite to be ran after the gqltest within our current backend integration test suite.
The sleep 5
exists because 1) this is temporarily stop-gap and 2) our site config change is eventually consistent and we need to wait (for changes to be restored from gqltest side effects).
This is not a complete solution to close #19763 but I think this is a good stop-gap to wrap up RFC 266 for the June 4th launch.
