When deploying with tls enabled in public
endpoints, ansible modules fails due SSL certificates
are self-signed.

This change adds a new variable to allow customization
on which endpoints ansible should connect.
Defaults to admin because admin auth parameters defaults
to admin endpoint.

The current module 'kolla_sanity' was written as a shim before full
shade support was added to Ansible. This should now no longer be needed,
we can implement the checks using Ansible provided modules.

Begin by updating the Keystone check to use 'os_auth' to fetch a token,
I think this is a good basic smoke test to verify Keystone is working.

TrivialFix

Change-Id: I1f03d428c380dfdbde5ef33e7ea43cbf5e9154ce

This change is needed for clarity. We have a kolla-ansible script.
We have a kolla-mesos repo. We plan to have a kolla-ansible repo.
Already we have had far too much confusion about whether we are
talking about the container or the project. Naming this kolla-toolbox
eliminates all of that confusion and its probably a bit more accurate
of a name too.
