Watcher consumes now notications sent by Nova services.
We have to configure Nova to publish its notifications into
the dedicated Watcher notification queue.

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.

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

Change I6c43eba941022a88851a199b56a6c20f017b9e71 seemed to have remove
most references to the SERVERS_CONSOLIDATION goal. Since this goal does
not currently exist in the actual code and all usages of it are for
samples or for tests, it is replaced with the DUMMY goal to avoid
confusion.

The OpenStackClients class provides a convenient way to create and
cache client instances. The idea behind this code comes from Magnum
[0].
The OpenStackClients class will act as the manager of other project's
clients, providing an easy way to fetch instances of said clients. This
will allow the clients to be cached.
An instance of OpenStackClients is created for every call that comes
into the decision engine and the applier, using the request context to
pass needed (domain id) parameters to get a Keystone session. This
instance should be shared as much as possible to avoid additional
unneccessary connections to the other services.
This class will also allow for the version of each client to be
configurable via the watcher.conf file.
The method by which a Keystone session is also changed to use the
keystoneauth1.loading library. In order to avoid DuplicateOptErrors
with the keystone_authtoken group used for the keystonemiddleware in the
API code, a new conf group named "watcher_clients_auth" is created. A
typical configuration using a password authentication scheme will look
like:
[watcher_clients_auth]
auth_type = password
auth_url = http://<server-ip>:<port>
username = <username>
password = <password>
project_domain_id = default
user_domain_id = default
