Collects PCI class, revision, and bus information for the pci-devices
collector, these metrics as well as vendor id and device id are
components which can be used to construct device information like
lspci output, which is how cyborg agent collects accelerator devices.
Accelerator device based scheduling is possible after ironic has such
information in place.

Eventlet, when monkey patching occurs, replaces the base
dns resolver methods. This can lead to compatability issues,
and un-expected exceptions being raised during the process
of monkey patching. Such as one if there are no resolvers.
As such, since we don't really need monkey patching of DNS,
and setting the flag should make the inspector CI jobs happier
where we don't need nor use DNS, AND tinycore may not be setting
a resolver configuration at all, which is the root of the failure
upon monkey patching that casues IPA to fail on start in certian
circumstances.
As a note, this has been performed on other projects due to
bugs. See Id9fe265d67f6e9ea5090bebcacae4a7a9150c5c2.

When no root_device hint is set, an MDRAID partition can be incorrectly
selected as the root device which causes installation of the bootloader
to the physical disks behind the MDRAID volume to fail. See the notes
in the referenced Story for more detail.
This change adds a little more specificity to the listing of block
devices.

When we added software raid support, we started calling bootloader
installation. As time went on, we ehnanced that code path for non
RAID cases in order to ensure that UEFI nvram was setup
for the instance to boot properly.
Somewhere in this process, we missed a possible failure case where
the iscsi client tgtadm may return failures. Obviously, the correct
path is to not call iscsi teardown if we don't need to.
Since it was always semi-opportunistic teardown, we can't blindly
catch any error, and if we started iSCSI and failed to tear the
connection down, we might want to still fail, so this change
moves the logic over to use a flag on the agent object which
one extension to set the flag and the other to read it and take
action based upon that.

Follow-up to commit c5b97eb781cf9851f9abe87a1500b4da55b8bde8.
Two things slipped through the cracks:
* ImageDownloadError was instantiated incorrectly, resulting in a wrong
error message. This was uncovered by using assertRaisesRegext in tests.
* We allowed calling write(None). This was uncovered by avoiding sleep(4)
in tests and enabling more failed calls before timeout.

The download retry interval was previously five seconds which is
not long enough to recover after a hard network connectivity break
where we may be reliant upon network port forwarding hold-down
timers or even routing protocol route propogation to recover
communication.
Previously the time value was 5 seconds, with 3 attempts, meaning
15 seconds total ignoring the error detection timeouts.
Now it is 10 seconds, with 10 attempts, meaning 100 seconds before
the error detection timeouts.

Socket read operations can be blocking and may not timeout as
expected when thinking of timeouts at the beginning of a
socket request. This can occur when streaming file contents
down to the agent and there is a hard connectivity break.
In other words, we could be in a situation like:
- read(fd, len) - Gets data
- Select returns context to the program, we do things with data.
** hard connectivity break for next 90 seconds**
- read(fd, len) - We drain the in-memory buffer side of the socket.
- Select returns context, we do things with our remaining data
** Server retransmits **
** Server times out due to no ack **
** Server closes socket and issues a FIN,RST packet to the client **
** Connectivity restored, Client never got FIN,RST **
** Client socket still waiting for more data **
- read(fd, len) - No data returned
- Select returns, yet we have no data to act on as the buffer is
empty OR the buffered data doesn't meet our requried read len value.
tl;dr noop
- read(fd, len) <-- We continue to try and read until the socket is
recognized as dead, which could be a long time.
NOTE: The above read()s are python's read() on an contents being
streamed. Lower level reads exist, but brains will hurt
if we try to cover the dynamics at that level.
As such, we need to keep an eye on when the last time we
received a packet, and treat that as if we have timed out
or not. Requests periodically yeilds back even when no data
has been received, in order to allow the caller to wall
clock the progress/status and take appropriate action.
When we exceed the timeout time value with our wall clock,
we will fail the download.

Adds a new poll extension to provide get_hardware_info and get_node_info
interfaces.
get_hardware_info will be used for node validation by ironic deploy
drivers.
get_node_info will be used for sending lookup data to IPA.
standalone mode is assumed as debug only, but it's not the case
considering the poll mode will be introduced, slightly updates the
description, also prevents the mdns lookup when standalone is true.
