The hacking checks enforce during the pep8 run functional validations of
the code to ensure deeper filters and code consistency. This change set
adds the hacking checks to the wathcer project. These checks were
seeded from the neutron project, which had a good set of base defaults.
This change set also updates the watcher project to be compliant with
these new hacking checks.

Currently we have to amend the code of the Planner
for each new added Watcher Action. This patch set will
modifying the DefaultPlanner class and leverage the

weights via the configuration file.
Documentation and unittest also be update in this patch.

The VM workload consolidation strategy sends 'down' instead
of 'disabled' to change nova-compute service state. This patch
will correct it. The same applies for enabling nova-compute service.

implement a new goal plugin. I also mention to define the efficacy
specification for a given goal.

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.

Partially Implements: blueprint get-goal-from-strategy
Change-Id: Ie394c12fe51f73eff95465fd5140d82ebd212599
In this changeset, I updated the 'goal_id' field into the AuditTemplate
to now become a mandatory foreign key towards the Goal model. I also
added the 'strategy_id' field into the AuditTemplate model to be an
optional foreign key onto the Strategy model.
This changeset also includes an update of the /audit_template
Watcher API endpoint to reflect the previous changes.
As this changeset changes the API, this should be merged alongside the
related changeset from python-watcherclient.

This patch adds a new load consolidation strategy based on a heuristic
algorithm which focuses on measured CPU utilization and tries to
minimize hosts which have too much or too little load.
A new goal "vm_workload_consolidation" was added which executes
the strategy "VM_WORKLOAD_CONSOLIDATION".
This work depends on the implemetation of the bug:
