Dmitry Tantsur c15ed6a48e Wait for at least one suitable disk to appear on start up 
Some kernel modules take substantial time to initialize. For example,
with mpt2sas RAID driver inspection and deployment randomly fail
due to IPA starting before the driver finishes initialization.

This problem is probably impossible to solve in a generic case, as
modern Linux environment do not have a notion of "hardware is fully
initialized" moment. All hardware is essentially hotplug.

To solve it at least for the simplest case, this patch adds a wait loop
on start up waiting for at least one suitable disk to appear in inventory.
Note that root device hints are not considered, as the node might not
be known at that moment yet.

ironic-python-agent

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.
