[Bug 980930] [NEW] nova client does not respect regions

[Andrew Glen-Young]

Public bug reported:

I am performing some tests with Keystone and multiple regions and have
discovered that nova client does not respect the --region argument
correctly.

Setup:
======

I have defined services within two regions:
- regionOne
- regionTwo

Tests:
======

# Ask for all endpoints
$ nova endpoints

Found more than one valid endpoint. Use a more restrictive filter
