Robert Church 8243f7d6ab Helm Backend for chart specific system overrides
Mirror the current infrastructure that we use for puppet based
provisioning of openstack services to enable system specific helm
overrides.

This commit comprises the backend to the sysinv API helm commands that
allow a customer to update the system provided overrides or introduce
new overrides for specific charts.

Four conductor RPC functions are provided to the API to gather system
overrides and namespaces for supported charts and chart bundles (i.e. an
application):
 - get_helm_chart_namespaces()
 - get_helm_chart_overrides()
 - get_helm_application_overrides()
 - get_helm_application_namespaces()

An application in this context is a set of supported charts that we
would deploy to support some specific functionality (i.e. a customized
openstack solution)

As with the puppet infrastructure, a CLI is provided to get the latest
system-only overrides for a given chart or bundle of charts that make up
an application. This is provided for development purposes and removes
user-provided overrides from the picture.

The following is the chart command syntax, a command to generate
override files for all supported namespaces of the ingress chart, and a
command to generate overrides for just the openstack namespace of the
ingress chart:
 - sysinv-helm create-chart-overrides <path> <chart> <specific namespace>
 - sysinv-helm create-chart-overrides /root/overrides ingress
 - sysinv-helm create-chart-overrides /root/overrides ingress openstack

The following is the application command syntax, a command to generate
override files for all supported namespaces of the all chart in the
chart bundle, and a command to generate overrides for all charts in the
chart bundle that support the kube-system namespace:
 - sysinv-helm create-app-overrides <path> <app> <specific namespace>
 - sysinv-helm create-app-overrides /root/overrides wr-openstack
 - sysinv-helm create-app-overrides /root/overrides wr-openstack kube-system
