Match the requirements for taskflow with
the openstack requirements (note the upstream
requirements are missing 'futures' and 'networkx')
and update the new hacking violations that were
detected due to the hacking requirement version
bump.

Previously to run a flow client code had to put together the flow,
an engine, logbook, flowdetail, and storage backend. This commit
adds two helper functions, run() and load(), so that simplest usecase
now looks like
taskflow.engines.run(flow)
Client code may also provide configuration for storage and engine if
needed, but if not needed it just works with defaults.
Engines are loaded via stevedore, as drivers in 'taskflow.engines'
backend. Now three entry points are defined in that namespace:
- 'default', for SingleThreadedActionEngine, used by default;
- 'serial', as another synonym for SingleThreadedActionEngine;
- 'parallel', for MultiThreadedActionEngine.

In order to move away from the existing flows having their
own implementation of running, start moving the existing
flows to be patterns that only structure tasks (and impose
constraints about how the group of tasks can run) in useful
ways.
Let the concept of running those patterns be handled by an
engine instead of being handled by the flow itself. This
will allow for varying engines to be able to run flows in
whichever way the engine chooses (as long as the constraints
set up by the flow are observed).
Currently threaded flow and graph flow are broken by this
commit, since they have not been converted to being a
structure of tasks + constraints. The existing engine has
not yet been modified to run those structures either, work
is underway to remediate this.

Add testcase that executes all examples from taskflow/examples
directory. For examples with somewhat deterministic output the output
is also checked.
This commit also fixes couple of examples broken by recent decorators
refactoring.

The examples will likely be easier to find
if they are colocated next to the rest of
the source tree. They can also be turned into
test cases in the future this way also.
