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

In this changeset, I implemented a Helper class to deal with
Monasca requests.

Specific exception should be thrown when cluster state
is stale. Current usage is to raise this exception if
compute_model.state is True.
Bug was describeid by Jean-Emile DARTOIS.

Closes-Bug: #1621855
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.

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.

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 merged the metrics_engine package into
the decision_engine one alongside the required changes to make
the tests pass.

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 made BaseClusterDataModelCollector instances
pluggable. This corresponds to "part 1" of the work items detailed
in the specifications.

Close-bug: #1600707
This patch fixes various typos and other nits in the strategies. It
also updates some of the log messages to be a little more operator
friendly.

In this changeset, I broke down the execute() method to sequentially
call 3 methods:
- pre_execute()
- do_execute()
- post_execute()
This changeset also removes the cluster model parameter from the
execute() method to now become a `model` property of a strategy which
is lazy loaded whenever needed.

In this changeset, I decoupled the notion of Goal from the Strategy
by making it a distinct object. Goals are plugins that can be loaded
just like for the strategies.
