Add standardized helm chart for appc

This is a standardization (based on helm community best practices)
of a Helm chart for the Application Controller (appc) in ONAP.

How to deploy the helm chart (outside of the parent onap chart) from
the local oom/kubernetes codebase.

Run local helm repository in the background:
$ nohup helm serve &

In kubernetes directory run:
$ make all

2 ways to install (--set are for testing purposes)
Full onap:
$ helm install onap --name onap --namespace onap --set global.pullPolicy=Never,mysql.replicaCount=2,appc.replicaCount=2

Appc only:
$ helm install setup --name onap-setup --namespace onap-apps
$ helm install appc --name appc --namespace onap-apps
