Chris Dent 4d525b4ec1 [placement] Add /reshaper handler for POST
/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
