[openstack-dev] [Neutron] Rename tenant to project: discussion

Really? I don't want to escalate, but I think that I'm entitled:
- to have an opinion on this, regardless of how much of the history I've read
- to express that opinion in response to an explicit request for "any feedback", particularly when no one else had responded to that call for nearly 24 hours.
FWIW, it's also fine with me that there is apparently a strong consensus _for_ this change, and I'm happy to reflect and ponder that my intuition might be wrong. I'd rather have stuck my neck out and contributed to a discussion, than be asked later "why did no one say anything?"

Some of them are just documentation and docstrings, but there are a lot of places, where variables are tangled: defined in DB, used in server, accessed by client. Most of places are just internal usages. The only thing where I've found 'public' information about tenants is 'help' command in neutron client.

My intuition is that we should just not do this change. The whole world
says 'tenant' for the 'tenant' concept, particularly in the context of
networking. Changing to a different term is just silly.
If you don't know the whole story why are you making these remarks?
But I haven't looked into the history. Perhaps there's some reason we
need to anyway.
