This makes platform independence easier. There are some cases where we
still use the yum module, where we use yum-specific module parameters.

Also switch use of the state 'installed' to 'present', which is
supported by all the package modules, whereas installed is supported by
the yum module only.

Connections default to 'public' interface when attempting to run
openstack commands.  This breaks setups where the network hosts are
separate from the controllers.

This change adds an ``openstack_interface`` variable to select the
correct endpoint to use, which defaults to ``internal``.

the flow.

Diskimage builder supports specifying a list of packages to install via
-p. We currently support this for the root image, but not IPA images.

This change adds a new configuration option, 'ipa_build_dib_packages',
that should be a list of additional packages to install in locally built
IPA images. This affects the following commands:

kayobe seed deployment image build
kayobe overcloud deployment image build

This depends on
https://github.com/stackhpc/ansible-role-os-images/pull/25.

Also adds an example to the documentation for the equivalent option for
root image.

Kolla ansible train adds a new command, kolla-ansible deploy-containers,
that will only deploy containers, and skips registration, bootstrapping
and configuration.

This change adds a new 'kayobe overcloud service deploy containers'
command to make use of the new kolla-ansible command.

The kolla-ansible CLI now requires the kolla_ansible python module to be
importable. We need to activate the virtualenv to make this work.

We no longer need to cd to the kayobe repo path, since all tested
versions of kayobe support pip installation.

Synchronises the globals.yml template, list of feature flags, and
inventory templates with the current state of kolla-ansible's
stable/train branch.
