In HA environment, after deleting a group, it can still be achieved from the other members in the cluster for a period of time.

Steps to reproduce.

1. Setup an Artifactory HA environment
2. Create a group:

   $ curl -uadmin:<password> -XPUT http://localhost:8081/artifactory/api/security/groups/group123 -H "Content-Type: application/json" -d"{}"

1. Issue a DELETE request for the created group:

   $ curl -uadmin:<password>  http://localhost:8081/artifactory/api/security/groups/group123 -XDELETE

1. Issue a GET group request to one of the other member in the cluster and notice that group detail returned in the output (instead "404")

   $ curl -uadmin:<password>  http://localhost:8081/artifactory/api/security/groups/group123

1. After a few minutes the results are sync
