Block Storage API v2 was deprecated during Pike cycle and is being
removed during Xena cycle, and current v3 API should be used instead.

Python introduced http.HTTPStatus since version 3.5,
and Wallaby has targeted a minimum version of python 3.6.
Change-Id: I45f732f0f59b8fae831bb6c07f4fdd98cdd7409a
Implements base method as well as some basic implementations to
retrieve time series metrics. Ceilometer can not be supported
as API documentation has been unavailable. Grafana will be
supported in follow-up patch.
Partially Implements: blueprint time-series-framework

The repo is Python 3 now, so update hacking to version 3.0 which
supports Python 3.
Fix problems found.
Update local hacking checks for new flake8.
Remove hacking and friends from lower-constraints, they are not needed
to be installed at run-time.

This patchset added a new audit type: event,
and the handler to execute event audit.

We have provided functions to get used and free resources in
class ModelRoot. So strategies can invoke the functions to
get used and free resources.

Use the general purpose threadpool when building the nova compute
data model. Additionally, adds thorough explanation about theory of
operation.
Updates related test cases to better ensure the correct operation
of add_physical_layer.

Implements the singleton general purpose threadpool for the decision
engine and associated tests.
A threadpool is a collection of one or more threads typically called
'workers' to which tasks can be submitted. These submitted tasks will
be scheduled by the threadpool and subsequently executed. How many
tasks will be executed concurrently is managed by the underlying
threadpool and its configuration. In Python the submission of tasks
to a threadpool returns an object called a 'future'. Futures provide
a method to interface with the task being executed that allows to
retrieve information about its state. Such as if it currently is being
executed, if it is waiting on a condition and if it has completed
succesfully. Finally, futures allow to retrieve what has been returned
by the submitted task.
In the case of most OpenStack projects instead of interfacing with native
Python concurrency the futurist library is used. This library provides
very similar interfaces to native concurrency with some extras such as
the wait_for_any method.
For more information about futurist or Python concurrency the following
references can be consulted:

When querying data from datasource, it's possible to miss some data.
In this case if we throw an exception, Audit will failed because of
the exception. We should remove the exception and give the decision
to the strategy.

Closes-Bug: #1847434
Reason:
When there is a compute node but no virtual machine,
the command 'watcher datamodel list' should display
the information of the compute node instead of return None.

This strategy is used to centralize VMs to as few nodes as possible
by VM migration. User can set a input parameter to decide how to
select the destination node.
