The new bp need to get audit type from audit,
so we need to add an audit parameter to do_execute

Currently, create audit with unspecified parameters will success.
This is not reasonable, we shoud return a FAILED status to
notify the admin user.

any audit or action plan whose goal has been re-synced
(upon restarting the Decision Engine).

Strategy provides parameters to customize algorithm behavior. End user
could query then specify parameters for their requirements.

Closed-bug: #1590357
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.

Change-Id: I2f697938db693acfa95b2c2fbecfdc1b733c93fd
In this changeset, I updated the 'goal_id' field into the AuditTemplate
to now become a mandatory foreign key towards the Goal model. I also
added the 'strategy_id' field into the AuditTemplate model to be an
optional foreign key onto the Strategy model.
This changeset also includes an update of the /audit_template
Watcher API endpoint to reflect the previous changes.
As this changeset changes the API, this should be merged alongside the
related changeset from python-watcherclient.

In this changeset, I refactored the strategy selector to now
look into the Watcher DB instead of looking into the configuration
file.

In some part in the code we import objects.
In the Openstack style guidelines they recommand
to import only modules.
We need to fix that.

Partial-Bug:1543101
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

Some Python class and packages need to be renamed
for a better compliance with the shared terminology
which provides a better understanding of Watcher
objects and components by every contributor.
This patchset is there to change the code structure by adding the folder
"strategies" and "loading".

Change-Id: I56fb24ee6762b3186eccde5983233e17bb227cc1
This patchset is there to change the code structure.
The objective is to flatten the project file tree by merging
'api/' and 'framework/' into a single package. This also contains
some tidy ups in package naming (like using only singular nouns).
This should only affect file/folder names and their subsequent
import paths wherever they were used.
