===============================
MultiCloud infra_workload API
===============================
We have two purposes for this API:
#. Integrate 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 this as parameters to HEAT
command line.
For further detailed design, please refer to https://wiki.onap.org/display/DW/SO+Casablanca+HPA+Design
Propose Change
==============
Multi-Tenant Support
--------------------
Request Headers:
>>>>>>>>>>>>>>>>
To support multi-tenants over the same cloud region, all APIs defined below
should support to accept the following optional headers which are used to
specify a tenant other than the default one associated with the cloud region.
::
"Project" : Tenant/Project ID or Name specified by API consumer, Optional
Example 1:
::
"Project: tenant1"
Example 2:
::
"Project: fcca3cc49d5e42caae15459e27103efc"
