Make direct call to controller in test_console_auth_tokens

In API unit testing, making call through WSGI is little bit overhead,
wherever applicable, unit tests can make direct call to controller
methods.

Some unit tests needs WSGI call to tests more than one plugin together.

This patch makes above cleanup in test_console_auth_tokens.

Partially implements blueprint v2-on-v3-api

VMware: Use datastore_regex for disk stats

VMware driver does not use datastore_regex when reporting disk
stats, while it is used when spawning instances.  As a result,
the available disk_free reported periodically can be different
from what is available when spawning.
