Description of problem:
Concurrent syncing of multiple composite content views to the capsule servers is failed with the error "A required lock is already taken by another task".

Version-Release number of selected component (if applicable):
6.7

How reproducible:
100 %

Steps to Reproduce:
1. Create two composite content views on Satellite web UI. Keep one or two content view same in both the composite content views. 
2. Promote the CCVs to the capsules environment. This will trigger separate Capsule sync for each of these CCVs for the capsule server.
3. Syncing a single CCVs to the capsules server starts in parallel and locks some resources and syncing any other CCVs to the same capsules will fail. 

Actual results:
Capsule sync failed with error "A required lock is already taken by another task".

Expected results:
The capsule should be sync without error.
