This patch set allows in case of NoMetricValuesForInstance exception
to continue the flow of Workload Stabilization strategy
instead of interrupting.

Developer should provide a detailled documentation about his strategy
algorithm to make it even easier to use by a Watcher end user.
I propose in this changeset a template for strategy documentation.
you will find also a example with basic consolidation strategy.

In this changeset, I fixed the issue with the basic server
consolidation strategy to now loop over all compute nodes
as expected instead of stopping after the first one.

In this changeset, I added debug logs to dump the cluster data model
copy structure (as XML) before and after the execution of the strategy.
By doing so, we can see the cluster data model structure that is
expected after the execution of the corresponding action plan.

When the action plan is empty,its state is still 'RECOMMENDED'.
I think it's should be 'SUCCEED'.

This patch set allows to use audit parameters for
workload-stabilization strategy and makes some little
refactoring.

plugin.

In this changeset, I implemented a small GMR plugin that converts
the cluster data model structure into an XML structure.

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.

Currently, create audit with unspecified parameters will success.
This is not reasonable, we shoud return a FAILED status to
notify the admin user.

This change is adding the main logic for the scoring module,
defines entry points for the scoring engine plugins and provides
a watcher-sync tool to enable Watcher database synchronization
without needing to restart any Watcher service.

In this changeset, I implemented the logic which cancels
any audit or action plan whose goal has been re-synced
(upon restarting the Decision Engine).

In this changeset, I refactored the whole Watcher codebase to
adopt a naming convention about the various elements of the
Compute model so that it reflects the same naming convention
adopted by Nova.

In this changeset, I implemented a background scheduler service
for Watcher and more particularly for the Decision Engine where
I made it create 2 types of job per cluster data model collector
plugin:
- An initial job that is asynchronously executed upon starting the
Decision Engine
- A periodical job that gets triggered every configurable interval
of time

In this changeset, I wrote down the documentation on how to implement
a cluster data model collector plugin for Watcher.
This documentation corresponds to part 1 of the associated
