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)

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 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.

computing an efficacy.

In this changeset, I created a new model named EfficacyIndicator
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 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.

Cold migration enables migrating some of the VMs which are not in active state (e.g. stopped). Cold migration can also be used for migrating active VM, although VM is shut down and hence unaccessible while migrating.

In this changeset, I fix the issue caused by the use of lazy
translations within the 'watcher-db-manage purge' subcommand.
This is caused by the PrettyTable dependency which performs
addition operations to format its tables and the __add__ magic
method is not supported by oslo_i18n._message.Message objects.
