[openstack-dev] [Ceilometer] Meters vs. Metrics

Can we keep it consistent ? The APIs have meter in them, so do the CLIs so we should really stick to that convention.

If Gnocchi is using metrics, I feel it should change to use meters or a V3 API proposed that changes it all.

Projects and Tenants still cause such massive confusion for the end user, let's not do it again. Saying they are equivalent does not stop the confusion and support effort when people say that the form allows them to create a project but they want a tenant.

tbh, i've been using them interchangeably -- i don't know if they are logically different. i believe gnocchi uses 'metric' term while current api uses 'meter' so we don't really have a common usage in api either. if i were to choose one, i'd lean more to using 'metric'.
