During ranger/logsearch/atlas startup, we need to make sure these services have permission to access for specific collections.
Also ranger plugins should be able to write into ranger collection as well.
There will be a new solr_cloud_util function to add user-roles to solr, which will update security.json on the zookeeper znode.
For newly added services with ranger plugins, solr will need to be restarted to generate the correct security.json on zookeeper.
Also this task will introduce a new custom security.json which can override that is used by default.
