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

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

Workers has been introduced into Decision Engine and Applier.
We can now tune ithe number of workers (threads) used by the
Decision Engine and the Applier services, by updating the Watcher
configuration file.

Today, the watcher Decision Engine is not relying on Ceilometer V2 API
to query the metrics necessary for the optimization algorithm.
This patchset update the documentation to use Ceilometer API with
watcher

The objective is to make it more explicit that the 'service' project
is referring to the keystone service.
This changeset also updated the documentation to stay under the
limit of 80 per line.

In current implementation is not easy to use ceilometer.
Watcher must query metrics from the Telemetry v2 API to allow an easiest integration with OpenStack components (especially devstack).
