Consistent Handling of Multiple Groups while the Initial cache loading and subsequent cache refresh in SSSD

[Kishore-237]

Description: SSSD should handle multiple groups consistently across both the Initial cache loading and subsequent cache refresh in to avoid access control inconsistencies.
Use Case: Users belonging to multiple groups in different OUs with same GIDs experience inconsistencies in access rights due to differences in primary and secondary cache behavior.
Current Behavior: The existing caching mechanism does not always reflect the same group memberships on both the Initial cache loading and subsequent cache refresh.
Expected Behavior: Group memberships should be synchronized while cache loading and refresh.
Potential Workarounds: Periodic restarts, which are not ideal for production environments.
