Enable all helm charts by default in parent chart

Enable all helm charts by default in parent chart

This is as a means towards obsoleting the oneclick scripts
from the Beijing release, in favour of directly using Helm.

From this point on, users of onap should use the follow
command:

helm install local/onap -n onap --namespace onap

Please refer to the official documentation for all the steps
required to deploy onap. Currently as a patched to be
merged: https://gerrit.onap.org/r/#/c/37871/
