IPA: previously cached netgroup member is not remove correctly after it is removed from ipa

[pbrezina]

BZ: https://bugzilla.redhat.com/show_bug.cgi?id=2162552

Description of problem:

If I have 2 netgroups - Test1 and Test2, I made Test1 a member of Test2. The client then caches this data. After removing test1 from test2, on the client getent netgroup will display the old data, even after the timeout or after using sss_cache -E

Version-Release number of selected component (if applicable):

RHEL7.9 fully patched on the 19th Jan 2023

How reproducible:

Steps to Reproduce:
1. Vanilla 7.9 install. Apply patches.
2. Join IDM ( 4.9.10 )
3. Create 2 netgroups. test1 and test2. 
4. Add test1 as a member of test2
5. Create users and assign different users to test1 and test2
6. On the client, getent netgroup ttest2
7. On the IDM, remove test1 from test2
 

Actual results:

On the client, wait for timeout or use sss_cache -E. Either way, the getent netgroup still shows test2 containing the test users1

Expected results:

The client should only show the users in test2


Additional info:

[root@rhel7-debug-client ~]# sss_cache -N
[root@rhel7-debug-client ~]# getent netgroup test2
test2                 (-,bob,lab.example) (-,tuck,lab.example) (-,builder,lab.example)
