Code Issues Proposed changes

Add long-running provider agent support

Browse Source 
This patch adds support for long-running provider driver agents to
the Octavia driver-agent.
It will fork a process for all of the enabled provider driver
agents at startup.

In addition, provider drivers may provide a provider agent also defined by a
setup tools entry point. The provider agent namespace is
"octavia.driver_agent.provider_agents". This will be called once, at Octavia
driver-agent start up, to launch a long-running process. Provider agents must
be enabled in the Octavia configuration file. An example provider agent
entry point would be:
.. code-block:: python

Provider Agents
===============
Provider agents are long-running processes started by the Octavia driver-agent
process at start up. They are intended to allow provider drivers a long running
process that can handle periodic jobs for the provider driver or receive events
from another provider agent. Provider agents are optional and not required for
a successful Octavia provider driver.
Provider Agents have access to the same `Stable Provider Driver Interface`_
as the provider driver. A provider agent must not access any other Octavia
code.
.. warning::
The methods listed in the `Driver Support Library`_ section are the only
Octavia callable methods for provider agents.
All other interfaces are not considered stable or safe for provider agents to
access. See `Stable Provider Driver Interface`_ for a list of acceptable
APIs for provider agents use.
Declaring Your Provider Agent
-----------------------------
The Octavia driver-agent will use
`stevedore <https://docs.openstack.org/stevedore/latest/>`_ to load enabled
provider agents at start up. Provider agents are enabled in the Octavia
configuration file. Provider agents that are installed, but not enabled, will
not be loaded. An example configuration file entry for a provider agent is:
.. code-block:: INI
[driver_agent]
enabled_provider_agents = amphora_agent, noop_agent
The provider agent name must match the provider agent name declared in your
python setup tools entry point. For example:
.. code-block:: python
octavia.driver_agent.provider_agents =
amphora_agent = octavia.api.drivers.amphora_driver.agent:AmphoraProviderAgent
noop_agent = octavia.api.drivers.noop_driver.agent:noop_provider_agent
Provider Agent Method Invocation
--------------------------------
On start up of the Octavia driver-agent, the method defined in the entry point
will be launched in its own `multiprocessing Process <https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Process>`_.
Your provider agent method will be passed a `multiprocessing Event <https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Event>`_ that will
be used to signal that the provider agent should shutdown. When this event
is "set", the provider agent should gracefully shutdown. If the provider agent
fails to exit within the Octavia configuration file setting
"provider_agent_shutdown_timeout" period, the driver-agent will forcefully
shutdown the provider agent with a SIGKILL signal.
Example Provider Agent Method
-----------------------------
If, for example, you declared a provider agent as "my_agent":
.. code-block:: python
octavia.driver_agent.provider_agents =
my_agent = example_inc.drivers.my_driver.agent:my_provider_agent
The signature of your "my_provider_agent" method would be:
.. code-block:: python
def my_provider_agent(exit_event):
