This change is to introduce a new rest api (v1/alarm/count) to
vitrage to provide counts of any alarms present in the system.
- It can optionally provide counts of alarms for all_tenants
similarly to the alarm api
- The rest api doc has been updated
- Unit test were added to test the api with and without
all_tenants as well as noauth
