This is the first of a series of commits that add the host-aggregates capability, as described on the blueprint page. This commit, more precisely, introduces changes to the Nova model: model classes related to aggregates have been added, as well as DB API methods to interact with the model; a sqlalchemy migration script plus a bunch of tests are also part of this changeset. Commits that will follow are going to add: - Extensions to OSAPI Admin, and related python_novaclient mappings - Implementation of the XenAPI virt layer - Integration of OSAPI and virt layer, via the compute_api - smoketests - openstack-manuals documentation These commits will be pushed for review not necessarily in this exact order.

"""Possible states for host aggregates.

An aggregate may be 'building', in which case the admin has triggered its

creation, but the underlying hypervisor pool has not actually being created
|
|
yet. An aggregate may be 'active', in which case the underlying hypervisor
|
|
pool is up and running. An aggregate may be in 'error' in all other cases.
