TENANT_ID in v2 is exactly equal to PROJECT_ID in v3. ID's are guaranteed
to be globally unique (implemented as service-defined UUID's) and are
url-friendly.

Names in keystone are freeform, user-supplied unicode strings. They may not
work in URL's without proper encoding and may collide in the future...

On that note, TENANT_NAME in v2 will become PROJECT_NAME in v3, however
we're also talking about namespacing project names to the owning domain, so
that two domains may have otherwise conflicting project names. Once we open
up the namespace, we can't go back, so we're going about it very carefully.
This may apply to user names, as well, but that's a subtly different
conversation.

If we do make this change then you also need to identify the domain for a
project name to be meaningful.

ID's will still uniquely identify a project regardless of domain or
deployment.
