The O-RAN standard was not being followed when resource address was
being specified with '*' as the "nodeName", which means that
subscription should be created to be notified about all nodes.
Test Plan:
PASS: Submitting POST request with '*' wildcard in resource address;
PASS: Rejecting POST for specific node when there is a subscription for
'*' in repo;
PASS: Rejecting POST for current node ('.') when there is a subscription
for '*' in repo.
