This adds the changes needed in the API and conductor level to support
creating updating and deleting nodegroups.

Magnum is sending notifications like cluster create but has no
details regarding the cluster, like cluster UUID. Notifications
from other OpenStack projects contain full detailed information
(e.g. instance UUID in Nova instance create notification).
Detailed notifications are important for other OpenStack
projects like Searchlight or third party projects that cache
information regarding OpenStack objects or have custom actions
running on notification. Caching systems can efficiently update
one single object (e.g. cluster), while without notifications
they need to periodically retrieve object list, which is
inefficient.

Story: #2006297
Task: 36009
To enable the rolling upgrade ability of Kubernetes Cluster, this
patch is proposing a new API /upgrade to support upgrade the
base operating system of nodes and the version of Kubernetes, even
add-ons running on the k8s cluster:
POST <ClusterID>/actions/upgrade
And the post body will be:
{
"cluster_template": 'dd9cc5ed-3a2b-11e9-9233-fa163e46bcc2',
"max_batch_size": 1,
"nodegroup": "production_group"
}

This changes the existing cluster APIs and the cluster conductor to
take into consideration nodegroups:
* create: now creates the default nodegroups for the cluster
* update: updates the default nodegroups of the cluster
* delete: deletes also the nodegroups that belong to the cluster
* cluster_resize: takes into account the nodegroup provided by the API

This is patch 3 of 3 to change the internal usage of the terms
Bay and BayModel. This patch updates Bay to Cluster in DB and
Object as well as all the usages. No functionality should be
changed by this patch, just naming and db updates.

Magnum needs to emit notifications for resource tracking, monitoring,
metering and auditing purposes so ceilometer can capture the events
and generate samples.
This commit leverage oslo.notify to send notifications when bay
resource operations are executed.

This patch aimed to reduce db call count when we invode k8sAPI.
For those user using bay name to do pod/rc/service operations, we
can saving a db call.

In k8s_conductor, lots of code will use bay_ident to get bay_uuid, kinds of
duplicated code, use retrieve_bay_uuid in conductor_utils to replace them.
retrieve_bay_uuid will return bay's uuid from bay_ident

Currently objects (pod/rc/service) are read from the
database. In order for native clients to work, they
must be read from the ReST bay endpoint. To execute
native clients, we must have one truth of the state
of the system, not two as we do now. This patch adds
changes for Replication Controller.
Also, please refer to the related-bug as to the temporary changes
done to make the test work for other objects namely pod,
service. These changes will be removed when the object from bay
patches for all the k8s objects are merged as part of a seperate
patch.

This allows common implementations to be reused later. Below is
the list of methods that were moved and renamed:
* handlers.k8s_conductor._retrieve_bay -> utils.retrieve_bay
* handlers.bay_conductor._get_baymodel -> utils.retrieve_bay
* handlers.k8s_conductor._retrieve_baymodel -> utils.retrieve_baymodel
* handlers.k8s_conductor._object_has_stack -> utils.object_has_stack
* handlers.k8s_conductor._retrieve_k8s_master_url ->

* handlers.k8s_conductor.Handler.k8s_api -> k8s_api.create_k8s_api
