Description of problem:
I did a POC this week for a customer where their openstack environment had approximately 50+ tenants. The problem is that by default all openstack tenants have a default security group called 'default'. The customer quickly got frustrated that they could tell from a list view of security groups which tenant belonged to each 'default' security group.  Please add a cloud_tenant column in the list view.

Version-Release number of selected component (if applicable):
5.5.2.4

How reproducible:
100%

Steps to Reproduce:
1. add an openstack provider that has multiple tenants
2. once the provider refresh is completed navigate to Clouds / Security Groups in CF
3. Attempt easily identify which security group maps to which tenants

Actual results:
we got a view of 50+ security groups all called default. The customer has to navigate to cloud_tenants and follow the relationship to figure out which default security group it belonged to.

Expected results:
Expected to see which tenant belonged to each openstack security group
