Resource(VCPU, memory and disk) capacity need to be calculated
through formula: capacity = (total-reserved)*ratio.

We have some new fields(vcpus_ratio, vcpus_used, ...)
in the Watcher ComputeNode. During the process of updating
data model by notifications, we need to get data from
placement.

The node.free_disk_gb does not take allocation ratios used
for overcommit into account so this value may be negative.
We do not need this field and plan to set disk to total disk
capacity and then remove disk_capacity.

check if the resource class(VCPU, memory, disk) in the return
dictionary. If they are, don't need to use dict.get() with a
default value because the parameters are required.

The api documentation is now published on docs.openstack.org instead
of developer.openstack.org. Update all links that are changed to the
new location.
Note that redirects will be set up as well but let's point now to the
new location.

The fields(vcpus, memory and disk_capacity) in the Watcher ComputeNode
do not take allocation ratios used for overcommit into account so there
may be disparity between this and the used count.
This patch added some new fields to solve this problem.

Add call_retry method for ModelBuilder classes along with configuration
options. This allows ModelBuilder classes to reattempt any failed calls
to external services such as Nova or Ironic.

Actually list_opts() return a list like[1], So we don't need to
convert list to dict and then convert to list[2].
The reason why we need to convert it before is to put together
the same group of configuration objects, but we don't need it
actually.
Now, the list_opts()'s result like this[3].
Reference:
[1]. [(Group1,[cfgObj1,cfgObj2....]),(Group2,[cfgObj3,cfgObj3....])..]

This lets all the ModelBuilder classes use one baseclass and forces
ClusterDataModelCollector's to pass the scope.
The scopes are still unused in the case of Ironic and Cinder.
The idea is to do several follow ups to this and in the end have a
similar method to query_retry in the datasources baseclass.

The datasources are only used by the decision_engine, however, they
are placed in a directory one level higher. This patch moves the
datasources code into the decision_engine folder.

We want to set the value of uuid field of Watcher ComputeNode
to hypversion id(as uuid). So we need to get hypervisor
information by uuid.

This error is caused because the condition "is not '':" is not always
true. Sometimes self.aggregation_method['node'] is u'' instead of ''.
This patch ensures that in both cases the behavior is the same.

This patch does two things:
1. replace instance's human_id with name.
2. remove ComputeNode human_id.
Now name field in Watcher Compute Data Model is availible.
Use name is better than human_id. For the reason, please see[1].

aggregate list and availability_zone list may return ironic type
compute nodes. When building compute data model we should check
the hypervisor_type and remove ironic compute nodes.

New datasource to retrieve metrics that can be configured in a
flexible way depending on the deployment. Current implemenation only
works with InfluxDB. Slight changes to datasource manager were
necessary because grafana metric_map can only be built at runtime.
The yaml configuration file can still be used to define metrics
but will require that five different attributes are specified per
metric.
Specific databases accesible through grafana can be defined by
creating 'translators' for these specific databases. This patch
introduces a base class for these translators and their methods.
In addition the first translator specific for InfluxDB is
created.
