Jay Faulkner a01646f56b Simplify heartbeating by removing use of select() 
Heartbeating in IPA has used select.poll() for years to workaround
a bug where changing the time in the ramdisk could cause heartbeats
to stop and never resume.

Now that IPA syncs time at start and exit, this workaround is no
longer needed. So instead, we'll revert to using threading.Event()
in order to make the code simpler and easier to understand.

Since we need this to be an eventlet-event, and not a standard-thread
event, also monkey_patch threading.

Additionally, there were a few completely unused backoff interval
values set, that were never applied. In respect of maintaining the
5+ years old behavior of not doing error backoffs, that code was
removed instead of being made to work.

Ironic Python Agent

Team and repository tags

Overview

An agent for controlling and deploying Ironic controlled baremetal nodes.

The ironic-python-agent works with the agent driver in Ironic to provision the node. Starting with ironic-python-agent running on a ramdisk on the unprovisioned node, Ironic makes API calls to ironic-python-agent to provision the machine. This allows for greater control and flexibility of the entire deployment process.

The ironic-python-agent may also be used with the original Ironic pxe drivers as of the Kilo OpenStack release.

Building the IPA deployment ramdisk

For more information see the Image Builder section of the Ironic Python Agent developer guide.

Using IPA with devstack

This is covered in the Deploying Ironic with DevStack section of the Ironic dev-quickstart guide.
