The aim of this patchset is to integrate taskflow in
the Watcher Applier. Taskflow will help us a lot to make
Action Plan execution easy, consistent, scalable and reliable.

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 extend the
default set of planner algorithms currently available in Watcher
using Stevedore.
The doc need to explain how create a new planner.

This should make our 'dummy' strategy available for use.
I also removed all previously defined default goals, which means
that they will have to define it themselves from now on.
This can also be useful for future integration tests.

In current implementation is not easy to use ceilometer.
Watcher must query metrics from the Telemetry v2 API to allow an easiest integration with OpenStack components (especially devstack).
