Julia Kreger e48a49c4c7 Retry on checksum failures 
HTTP is a fun protocol.

Size is basically optional. And clients implicitly trust the server
and socket has transferred all the bytes. Which *really* means you
should always checksum.

But... previously we didn't checksum as part of retrying.

So if anything happened with python-requests, or lower level
library code or the system itself causing bytes to be lost off the
buffer, creating an incomplete transfer situation, then we wouldn't
know until the checksum.

So now, we checksum and re-trigger the download if there is a
failure of the checksum.

This involved a minor shift in the download logic, and resulted in
a needful minor fix to an image checksum test as it would loop for
90 seconds as well.

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.
