Watcher applier should be able to live migrate instances on any storage
type. To do this watcher will catch error 400 returned from nova if we
try to live migrate instance which is not on shared storage and live
migrate instance using block_migrate.
Added unit tests, changed action in watcher applier.

In watcher/common/ceilometer_help.py:129,
there is an unused parameter, called limit:
def get_last_sample_values(self, resource_id, meter_name, limit=1):
In the next line, there is a method call which can take this
currently unused 'limit' parameter. Probably, passing this 'limit'
parameter to the query was originally intended, however it wasn't
added to the query call.

Although it was proposed via python-watcherclient, the feature was
not implemented on the Watcher API.
As the notion of host aggregate is currently unused in Watcher,
decision was made to only implement the filtering of goal within
the Watcher API whilst removing the host_aggregate filter from the
Watcher client.
Thus, this patchset adds this missing functionality by adding the
'goal' parameter to the API.

As we had a low test coverage on actions, I added some more tests
with this patchset. This actually revealed a small bug (typo) in
"change_nova_service_state" which has been fixed in here.
Note that Tempest test also cover these action via the
basic_consolidation strategy.

In the Openstack style guidelines they recommand
to import only modules.

execute an action plan using the 'basic_consolidation' strategy.

In order to accept the requirements contract defined in
openstack/requirements, we need to sync with the master branch of that
project's global-requirements.txt and test-requirements.txt files.
Most of the changes are just version changes and nothing major. The
only major change is:
1) The twine dependency is removed, and therefore the pypi tox
environment was also removed.

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

As of now we only have a single scenario which creates and
successfully executes the DUMMY goal.
This patchset adds a new scenario which creates and executes the
BASIC_CONSOLIDATION goal mapped to the 'basic' (sercon) strategy.
The documentation has also been updated to take into account the
multinode configuration.
