===============================
MultiCloud infra_workload API
===============================
we have two purposes for this API:
#. Intergrate SO and Multicloud.
#. Generic API for SO to talk to different Multicloud plugins.
Problem Description
===================
Currently HPA flavors are returned by OOF to SO and SO copies these flavors in
the Heat template before sending the Heat template to Multicloud. In Casablanca
instead of SO making changes in the Heat template the flavor information will be
provided to Multicloud and Multicloud will pass these as parameters to HEAT
command line.
The detail design refer to https://wiki.onap.org/display/DW/SO+Casablanca+HPA+Design
Propose Change
