Resolve the helm templates
Resolving the helm templates for each of the apps in the compositeApp by utilizing the helm libraries and thus getting the sorted templates with all values rendered. This is a subtask of adding instantiation APIs. Issue-ID: MULTICLOUD-1041 Signed-off-by: Rajamohan Raj <rajamohan.raj@intel.com> Change-Id: Id4fddda69b5276b2409d835723b11367400ab6ea
