Add tempauth back to /info

Our functional tests are skipping Account ACL tests when using tempauth
because it does not register itself with in swift.common.utils._swift_info

Add the register_swift_info call back to the filter_factory function in the
tempauth from which it was removed, and add a test to validate creating the
filter will add the middleware to global info dict.
