Amulet doesn't find deployed units

The amulet Talisman code
<https://github.com/juju/amulet/blob/34de3714902e1f5cad237340ea92e09776dbe3c6/amulet/sentry.py#L352>
only creates sentries for services (applications) that are in the
deployment schema. The Kubernetes Core bundle tests just don't work.

I looked at the Canonical Kubernetes bundle and those tests load the bundle
from the bundle file
<https://github.com/juju-solutions/bundle-canonical-kubernetes/blob/master/tests/20-basic-component-check.py#L17>,
and create a Deployment with that bundle. That approach seems to be
working. I like that approach best since the tested deployment will change
when the actual bundle changes.
