Add tests for barclamp_keystone

[mmnelemane]

Added basic feature tests for keystone with

Access to keystone resource lists(eg: services, projects, users, hosts etc) through openstackclient
create/delete users and project using openstackclient command line interface
Added new openstack.rb function to the cct library to include command for "openstack host list"

I think all (or most of) the OpenStack CLI code is already available upstream. See i.e. https://github.com/openstack/python-openstackclient/blob/master/functional/tests/identity/v2/test_project.py . Why are not using that code (and extend it if needed)?

[mmnelemane]

Would it make sense to add checks for SSL,PKI and Tokens instead of using openstack client tests here ?

[toabctl]

The client uses SSL and PKI tokens if that's what was deployed. AFAIR we agreed to not check things like "Feature A was enabled, now check if Feature A is really enabled". That will be done with crowbar_batch. Or am I missunderstanding your question?

[dirkmueller]

@mmnelemane can you rebase this?

https://ci.suse.de/job/openstack-mkcloud/15243/ failed in cct

Ambiguous match of "the chef role "rabbitmq-server" exists on admin node":

[mmnelemane]

@bmwiedemann: corrected that.
