Okay, I have prepared the patches for all branches (11...HEAD). Each
version needs minor changes in the test, the code doesn't need much
change. Some notable changes in the tests:
1. I have removed the conf change for max_logical_replication_workers
on the publisher node. We only need this for the subscriber node.
2. After creating the new subscriptions wait for initial
synchronization as we do for other tests.
3. synchronous_standby_names need to be reset for the previous test.
This is only required for HEAD.
4. In PG-11, we need to specify the application_name in the connection
string, otherwise, it took the testcase file name as application_name.
This is the same as other tests are doing in PG11.

Can you please once verify the attached patches?
