This PR adds a test to catch deadlocks when using xDS to resolve the address of the xDS management server, resulting in the creation of nested xDS channels. The fix for the bug was initially submitted in #8011 and later in #8445.
Tested
Verified that the deadlock can be reproduced in 2-3 runs when the fix in #8445 is not included. The deadlock is resolved after including #8445.
