This change passes the agent object into extensions, such that
they may call agent methods as needed. It also causes async
commands to force a heartbeat immediately after completing the
command. This allows Ironic to get a heartbeat and continue
work as quickly as possible, while also allowing deployers to
configure Ironic (agent) to heartbeat less often.

sync_command and async_command in ironic_python_agent/extensions/base.py
are implemented so that they change decorated method signature,
which is really bad practice. Example:
@sync_command
def orig_method(self, **kw):
...
sync_command decorator returns lambda which has one additional
argument 'command_name'
def sync_command(func):
def decorated(self, command_name, **kw):
...
func(self, **kw)
...
return decorated
Additional parameter 'command_name' is moved from decorated function to
decorator signature in both decorators. Every call of decorated functions
is fixed, BaseAgentExtension.execute is updated to not send this extra
argument. BaseAgentExtension.__init__ automatically generates command_map
from decorated methods.

Previously this code was calling processutils.execute incorrectly,
expecting it to return the exit code. This change:
* fixes calls to processutils.execute
* fixes related tests

Expose an async decom.erase_hardware command in the API. Executing
this command simply calls erase_devices on the loaded HardwareManager
implementation.

Removed creating separate extension manager for flow extension.
Instead, have made flow extension using the same extension manager
instance which is initialized in agent. It fixes circular
extension loading in stevedore.

Introduce `serializable_fields` to express which class attributes
to be serialized.
Get rid of OrderedDict. Just replacing it with regular dict.

This was broken when extensions/ subdirectory was created.
Also add test to ensure this doesn't break again.

The parameters sent to `prepare_image` changed in
https://review.openstack.org/#/c/86490/
This patch brings `prepare_image` up to date with that change.
It also changes the way configdrive is written to disk, to match
that Ironic is now allowing Nova to build an ISO partition and
send the raw image to the agent.
This patch also swaps out subprocess.call for processutils.execute
in the standby module, since the commands were being changed anyway.
Lastly, this patch changes the expected `hashes` dict to be a
string parameter called `checksum`, to match what glance returns.

Prior to the (sync|async)_command decorators, extension methods had to
construct command results themselves, which required that they have
the name of the command being executed.
When the async_command decorator was introduced, we wanted to maintain
the current command interface, so that a command could be made
asynchronous simply by adding the decorator.
The introduction of the sync_command decorator allows us to satisfy
this objective, without requiring decorated methods to accept a
command_name. This patch modifies both decorators to no longer pass
the command_name argument, and modifies existing command methods not
to expect one.

Instead of special-casing syncronous commands, add a decorator similar
to @async_command(), which can be used to decorate extension methods
for execution as a synchronous command.

Move extensions under an ironic_python_agent.extensions module. This
change also moves the @async_command() decorator into the base
extension module.
