In one integrated cloud env, there would be many solutions, which would
make the compute resource strongly relocated. Watcher should listen to
all the notifications which represent the compute resource changes, to
update compute CDM. If not, the compute CDM will be stale, Watcher
couldn't work steadily and harmoniously.

which nodes are disabled by Watcher and which are not by Watcher.

This patch adds instance metadata in the cluster data model. This
is needed for Noisy Neighbor strategy.

Improves tracking independent workflows. A log adapter
was added to provide an easy means of prepending publisher
ID and event type information.

In this changeset, I use https://review.openstack.org/#/c/362730/
as an example to make the existing ModelRoot fully graph-based.

When we receive a incoming 'service.update' notification
from nova, with disabled: false, we should set the related
compute node status to ENABLED.

In this changeset, I implemented the notification handling (Rx only)
system for consuming incoming notifications, more especially the Nova
ones. The notifications handlers also contain the logic which
incrementally updates the Compute model.
