Services are now identified by uuid instead of database id to ensure
uniqueness across cells.
GET /os-services returns a uuid in the id field of the response
from API microversion 2.53(maximum in Pike)
This patch set updates default Nova API version to 2.53.

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.

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

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.

The BaseException class defined in exceptions.py is shadowing the
built-in BaseException class of the Python exception hierarchy, which
could potentially cause confusion.
This removes the BaseException definition and replaces it with the
existing WatcherException object. Instantiations of the
IllegalArgumentException are also changed to use the message kwarg.

In watcher, an audit generates a set of actions which
aims at achieving a given goal (lower energy consumption, ...).
It is possible to configure different strategies in order to achieve
each goal. Each strategy is written as a Python class which produces
a set of actions. Today, the set of possible actions is fixed for a
given version of Watcher and enables optimization algorithms to
include actions such as instance migration, changing hypervisor state,
changing power state (ACPI level, ...).
The objective of this patchset is to give the ability to load
the actions dynamically in order to apply the Action Plan.
