Stack lifecycle scheduler hint

Registered by William C. Arnold

A heat provider may have a need for custom code to examine stack requests prior to performing the operations to create or update a stack. After the custom code completes, the provider may want to provide hints to the nova scheduler with stack related identifiers for custom code processing for scheduler plug-in processing within Nova. The blueprint describes a mechanism whereby the stack the stack id, root stack id, stack resource id, stack resource name and the path in the stack (as a list of tuples, (stackresourcename, stackname)) can be passed to nova by heat as scheduler hints, to the configured schedulers for nova.
