/reshaper provides a way to atomically modify some allocations and inventory in a single transaction, allowing operations like migrating some inventory from a parent provider to a new child. A fair amount of code is reused from handler/inventory.py, some refactoring is in order before things get too far with that. In handler/allocation.py some code is extracted to its own methods so it can be reused from reshaper.py. This is done as microversion 1.30. A suite of gabbi tests is provided which attempt to cover various failures including schema violations, generation conflicts, and data conflicts. api-ref, release notes and rest history are updated Change-Id: I5b33ac3572bc3789878174ffc86ca42ae8035cfa Partially-Implements: blueprint reshape-provider-tree

Microversion 1.30 of the placement API adds support for a
|
|
``POST /reshaper`` resource that provides for atomically migrating resource
|
|
provider inventories and associated allocations when some of the inventory
|
|
moves from one resource provider to another, such as when a class of
|
|
inventory moves from a parent provider to a new child provider.
|
|
|
|
.. note:: This is a special operation that should only be used in rare
|
|
cases of resource provider topology changing when inventory is in
|
|
use. Only use this if you are really sure of what you are doing.
