I need to add a new ceilometer meter for getting the tenants (or) Projects from the openstack keystone.

keystone tenant-list will be returning the list of active tenants.

I need to add the result of tenant-list to the ceilometer meter.

There is already existing meter similar to the same is identity.project.created, identity.project.deleted etc.,

Likewise, I need to add the identity.project.all which will return all tenants available.

Someone let me know the way for achieving the same.
