This verifies that making a configuration change to one of Umbrella's
subcharts results in only the application (DaemonSet, Deployment or
StatefulSet) for that subchart being updated. No other subchart's
application should be updated.
This only validates subcharts from openstack-helm-infra.
Validating the remaining subcharts from openstack-helm will
be done in the future.
OpenStack Umbrella's default values for rabbitmq was configured
to use a host path. This is so rabbitmq retains its data
between StatefulSet changes. Otherwise components fail to authenticate
with rabbitmq after the rabbitmq pods have been recreated. The
OpenStack Umbrella Chart will use the `standard` storage class
by default since that's what is provisioned via minikube.
