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 a common generic dynamic loader for plugins,
such as for custom Actions, Strategies, Planners, etc.

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)

It implements one of the algorithm of Intel thermal POC.
It extends the BaseStrategy class, getting the Outlet
metrics of servers via Ceilometer, and generates solutions
when the outlet Temperature is greater than threshold.
current threshold is hard-coded, will make it configurable
in the next patches.

"admin_user", "admin_tenant_name", "admin_password" and "auth_uri"
are options which are imported from the "keystone_authtoken" group,
itself being part of the "keystonemiddleware" 3rd-party library.
The problem is that these options are imported at 2 different
locations in the codebase:
- watcher/applier/manager.py
- watcher/common/keystone.py
Removed one from the applier.

The prepare_service() function is defined both in watcher/service.py
and in watcher/common/service.py.
These 2 needed to be merged into a single one
to avoid code duplication.
At the same time, the watcher/service.py only contains this function,
so I removed that file.

As of now, the glossary defined in our documentation reflects the
current state of the codebase. In order to avoid any discrepancy
between the codebase and each definition, the objective here is to
gather both in a single place and link it into the rst documentation
via a custom directive.
Also re-aligned the requirements with liberty for doc.
