Description of problem:

If only a subset of zones are allowed to sync among each other, ideally remaining zones should not be listed as source in "sync status" cmd output.

For eg., Out of zg1-1, zg1-2 , zg1-3 zones, if zonegroup policy is set to allow symmetrical sync between zg1-1 & zg1-3 zones only, 

- zg1-3 should not be listed as source in the sync status of zg1-1 & zg1-2 
- Likewise, zg1-1 & zg1-2 should not be listed as source for zg1-3

However all the zones are still listed in the 'sync status' output. It may not be easy to improve the cmd output here as  it should consider all the policies set (symmetrical/directional) for all the buckets across the zonegroup.

This bug is to check if its feasible to address it.


Note: 'bucket sync status' is updated as per the policy set. 

Version-Release number of selected component (if applicable):
6.0

How reproducible:
Always

Steps to Reproduce:
1. Create three zones (zg1-1, zg1-2, zg1-3) in a zonegroup zg1
2. Create a policy at zonegroup to allow sync among only two zones (zg1-1, zg1-2) 
3. Execute 'sync status' on zones zg1-1, zg1-2, zg1-3 & verify if the source-zones are updated accordingly
