Exceptions should be reraised with just "raise" and not "raise e" to
preserve the traceback. This also addresses a couple cases where the
catching and reraising of the exception was not actually doing anything.

This patch set adds efficacy indicators for workload_balancing
goal (that includes workload_stabilization and workload_balance
strategies so far).

This patch replaces voluptuous with JSON-schema to validate
efficacy indicator since in watcher we want to remove voluptuous
and use JSONSchema as our only JSON validation tool to keep consistency.

maintain one compute node without having the user's application
been interruptted.
It will firstly migrate all instances from the maintenance node
to one backup node. If not, it will migrate all instances,
relying on nova-schduler.

AverageCpuLoad and MigrationEfficacy efficacy indicators are not used.
This patch removes unused indicators.

Added strategy to identify and migrate a Noisy Neighbor - a low priority VM
that negatively affects peformance of a high priority VM by over utilizing
Last Level Cache.

As instance migration cost is petty compared to the cost of
compute node release, I update the way to compute the global
efficacy for a server consolidation goal. The new formula is simplest
and it's only based on compute node.

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.

This patch updates the applier's abstract methods to be consistent
with other abstract methods of similar nature.
Also included are a few other miscellaneous changes.

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 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
specification.

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 goal name 'airflow optimization' must be synched with the
entry point name.
The strategy name 'uniform airflow' must be synched with the
entry point name.

In this changeset, I wrote a documentation detailing how one can
implement a new goal plugin. I also mention to define the efficacy
specification for a given goal.

In this changeset, I added the new Efficacy, EfficacySpecification

computing an efficacy.

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.
