In this changeset, I added composite contraints on models that
were currently subject to an implicit uniqueness.
This composite constraint takes as an input the name and the deleted
columns.
The 'deleted' column is 0 by default and is updated with the value of
the associated 'id' column upon soft deletion.
What this means is that this composite constraint guarantees the fact
that we can hold many soft deleted records holding the exact same name.
Indeed, the value of the deleted column will be different whilst
forbidding 2 non-soft deleted records with the same name as their
associated 'deleted' value will be 0 and subsequently violates the
constraint.

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.

There's a number of places where a field of an object is named "type",
which isn't good thing. Actually type is keyword in python, so wherever
I found type used in models/api/object/test, I have fixed it to
audit_type in the audit files

In this changeset, I refactored the DB filter system to support
comparison operators using a django-like syntax.
A filter can take 2 forms:
- "<FIELDNAME>" which is a syntactic sugar for "<FIELDNAME>__eq"
- "<FIELDNAME>__<OPERATOR>" where <OPERATOR> is the comparison operator
to be used.
Here is the list of the supported operators:
- 'eq' (==)
- 'neq' (!=)
- 'gt' (>)
- 'gte' (>=)
- 'lt' (<)
- 'lte' (<=)
- 'in' (in)
- 'notin' (not in)

computing an efficacy.

which is responsible for storing information regarding the efficacy
indicators that were computed by the strategy in its solution. Every
efficacy indicator should relate to a single Action Plan.

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.

As a pre-requisite for being able to query the database for objects
that are expired, I need a way to express date comparison on the
'deleted_at' field which is common for every Watcher object. As they
are coming from mixins, I decided to implement these filters with a
syntax borrowed from the Django ORM where the field is suffixed by the
comparison operator you want to apply:
- The '__lt' suffix stands for 'less than'
- The '__lte' suffix stands for 'less than or equal to'
- The '__gt' suffix stands for 'greater than'
- The '__gte' suffix stands for 'greater than or equal to'
- The '__eq' suffix stands for 'equal to'
I also added a 'uuid' filter to later on be able to filter by uuid.

As we can see in the codebase, we have 3 "Status" enums which are
located at:
- watcher/objects/action.py
- watcher/objects/action_plan.py
- watcher/objects/audit.py
So I renamed them from "Status" to "State" to be consistent with
the DB schema.

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, ...).
This patchset add the possibility to store several parameters
for an Action.
The parameters store info that the custom Action needs.
The parameters provided as tuples with the following fields:
(parameter_name, parameter_type).
It remove also the deprecated attributes
(src,dst,description)
