At present the check for which transport to use references a
configuration option that has been removed.
Update check to test for current configuration option plus
add a check for presence of `tls-certificates` relation.
Also remove insecure option and add verify option to allow
control of verification including providing own CA certificate
bundle.
Reference for verify option:

Currently interacting with functions in zaza.model requires the
model to be passed in. This has resulted in multiple calls to
get_juju_model(). It is cleaner to push these calls down into
the model wrapper and make the model_name an optional
argument. In addition, the current model name is now cached
without having to check the os.env each time.
Unfortunately this has resulted in the signature changing on a
great many function so this diff is bigger than would normally
be desirable.
* Add OpenStackAPITest class which can be used by OpenStack API
charms. It provides the framework for common tests like pause
and resume. It also provides lower level entites like an
authenticated keystone session.
* Add generic openstack resource managment functions to
zaza.utilities.openstack. These are based on existing functions
in charmhelpers. Main difference is that they use tenacity to
manage retry logic and throw AssertionError if then required state
is not reached rather than returning True/False
* Add image management functions to zaza.utilities.openstack.
* Add set of glance setup/configuration/tests. These are equivalent
to the existing glance amulet tests with all the introspection
tests removed (see below for more detail).
