devstack produces a file called clouds.yaml already with credentials in
it. Rather than producing our own config file to run functional tests,
just consume the clouds.yaml file that's already there.

The check-glanceclient-dsvm-functional gate job was failing due to the
functional tests not picking up valid OpenStack credentials.
Update how we aquire credentials -- fixes side effect of how tox 2.0
handles environment variables.

This will allow adding 'check-glanceclient-dsvm-functional' tests in
the gate, similar to:
* check-novaclient-dsvm-functional
* check-keystoneclient-dsvm-functional
* check-neutronclient-dsvm-functional
* etc
