In this changeset, I added the /strategies endpoint to the Watcher
API service.
This also includes the related Tempest tests.

In this changeset, I changed the Strategy base class to add new
abstract class methods. I also added an abstract strategy class
per Goal type (dummy, server consolidation, thermal optimization).
This changeset also includes an update of the /goals Watcher API
endpoint to now use the new Goal model (DB entries) instead of
reading from the configuration file.

API.

We have to check Audit Type and Audit State to make sure
these parameters are in valid status.
Also, we provide default states for the next attributes:
- 'audit_template' is required and should be either UUID or text field
- 'state' is readonly so it raises an error if submitted in POST
and is set by default to PENDING
- 'deadline' is optional and should be a datetime
- 'type' is a required text field

Due to importing modules rather than functions and decorators directly,
@abc.abstract and 'raise NotImplementedError' were added to the
.coveragerc file. Since abstract methods are not testable, this will
give us a more accurate representation of our coverage.

and LOG vars.

The list of possible states for Action Plan objects was outdated, and
was updated to match the state machine diagram. A reference to the
state machines for Audits and Action Plans were added to the glossary,
and the descriptions of each state were moved to the sections containing
the state machines within the Architecture page.

This patch adds a new load consolidation strategy based on a heuristic
algorithm which focuses on measured CPU utilization and tries to
minimize hosts which have too much or too little load.
A new goal "vm_workload_consolidation" was added which executes
the strategy "VM_WORKLOAD_CONSOLIDATION".
This work depends on the implemetation of the bug:

Watcher sample configuration file groups parameters from
various projects and the watcher project ones. This makes it
tricky to review updates on configuration parameters.
It is inconvenient for developer if the add/remove/change some
configuration options cause they need to take care about the
config.sample file.
The sample configuration file should be available into HTML doc.
This patchset:
. removes the file /etc/watcher/watcher.conf.sample
. adds an admin script tool to be able to built it, by using tox
. includes a new section 'Watcher sample configuration files' into
the doc source files
. uses sphinx extension oslo_config.sphinxgenconfig

In watcher/applier/workflow_engine/default.py, we are checking the
return value of action.execute(). As the "TODO" above indicates it
(line 118), we should get rid of this and only flag an action as
failed if an exception was raised during its execute(). We will
need to update the related unit tests.
