Corey Bryant 981b86a3a1 V3 authtoken update and glance v1 icehouse
Update the keystone authtoken template section to explicitly
specify v3 API when it is in use. This prevents errors that
result in "Could not find versioned identity endpoints when
attempting to authenticate".

Along with this change we remove the tests that verify the
keystone_authtoken section as it's generally agreed that
functional testing should catch issues with this config.
Also update requirements to fix pyyaml dep of charm-tools.

Finally get glance v1 client for icehouse. Previously the
image virt type was qemu and the compute node virt type was
kvm. This works for deployments prior to rocky but in rocky
this causes the image type filter to return no valid hosts.
An update to charmhelpers has removed the default behaviour
of setting the virt type to 'qemu' by default. Due to a bug
in icehouse updating glance image properties using the v2 api
fails (See Bug #1371559) so for icehouse deploys get a v1
client.
