When inspecting block devices on a node, discover and
report the /dev/disk/by-path/XXX name along with the
/dev/XXX block device name.
The second name does not change between Linux system
reboots and has greater chances to be the same across
similarly configured nodes.

Adds an extra field ``biosdevname`` to network interface inventory
collected by ``default`` inspection collector (which collects the whole
inventory returned by hardware manager) of ironic-python-agent.
This feature requires biosdevname utility to collect the bios given NIC
names. The tooling module for tinyIPA is created for the same purpose.
For CoreOS IPA pxe images, biosdevname tooling module is limited,
because Docker repository is created and embedded into CoreOS pxe
images. The Docker repository uses debian to download the packages.
Debian does not have biosdevname package.
Adds an export variable TINYIPA_REQUIRE_BIOSDEVNAME. Set this
variable to ``true`` in your shell before building tinyIPA.

This patch is adding a new cleaning step called "erase_devices_metadata"
to the GenericHardwareManager. This step is responsible for erasing the
metadata of the disks present in the node (partition tables, signatures,
filesystem identifiers etc...).
It's important to note that the "erase_devices" cleaning step will also
remove all these metadatas (because it will zero/shred the whole disk)
but, it takes a lot of time to run and for some usages of Ironic only
cleaning the device metadata and leaving the data from previous tenants
on the disk after the machine is recycled is fine. That's the use case
for systems using Ironic just to install the same base image onto many
nodes which will run another cloud on top afterwards (TripleO).
The new cleaning step has a default priority of 99, so it should run
before the "erase_devices" cleaning step so that we can guarantee that
the metadata was removed even in case of a failure when cleaning the
disks.
The version of the GenericHardwareManager was bumped to "1.1" with the
addition of this new clean step.
This patch make use of the "destroy_disk_metadata" method from ironic-lib
to get rid of the metadata.

When matching the root device hints passed to Ironic and the devices
present in the disk, the logic to the "size" attribute was different was
outside the main loop. This patch refactors that uses the same loop for
matching the size attribute, improving a little the readability.
This patch also makes sure that we convert the value of "size" to
integer before attempting to match it.

To support multi-tenant networking in Ironic we need to be able to
discover not just the NICs a baremetal machine has but also the physical
connectivity to switches in the network.
This patch collects LLDP (Link Layer Discovery Protocol) data as part of
the list interfaces stage of the generic hardware manager. This
information can then be processed by the ironic inspector to populate
the local link information on each ironic port.
The processing done on this data in ironic python agent is limited, this
is to allow for server side processing hooks to process as much or as
little of the data as they want. This is to allow for multi-vendor
environments that might use different parts of the LLDP packet to use a
generic ramdisk and configure the processing server side using inspector
plugins.
Reserved fields switch_port_descr and switch_chassis_descr have been
deprecated for removal in Ocata in favor of passing the whole packet.

In order to support a more complex syntax for root device hints (e.g
operators: greater than, less than, in, etc...) we need to stop relying
on the kernel command line for passing the root device hints. This patch
changes this approach by getting the root device hints from a cached
node object that was set in the hardware module.
Two new functions: "cache_node" and "get_cached_node" were added to the
hardware module. The idea is to facilitate the access to a node object
representation from the hardware extension methods without changing
method signatures, which would break compatibility with out-of-tree
hardware managers.
Note that the new "get_cached_node" is just a guard function to
facilitate the tests for the code.
The function parse_root_device_hints() and its tests were removed since
it's not used/needed anymore.

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.

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.
Add a new hardware manager method initialize_hardware, which gets
run on start up before other hardware manager method invocations.
The generic implementation is to call udev settle and wait for
at least one suitable disk device to appear with the hardcoded
timeout of 15 seconds. Also preload the IPMI modules instead of
calling modprobe every time the inventory is requested.

Presently should the ATA erasure operation fails, IPA halts the
cleaning process and the node goes to CLEANFAIL state as a result.
This failure could be the result of a previous cleaning failure
that left drive security enabled, for which code has been added
in an attempt to address this case by attempting to unlock the
the drive.
In the event that an operator wishes to automatically fallback to
disk scrubbing operations, the capability has been added through
a driver_internal_info field "agent_continue_if_ata_erase_failed"
that can be set to True, however defaults to False keeping the
same behavior that IPA presently exhibits in the event of ATA
erase operations failing.

In the DIB build the DHCP code (provided by the dhcp-all-interfaces element)
races with the service starting IPA. It does not matter for deployment itself,
as we're waiting for the route to the Ironic API to appear. However, for
inspection it may result in reporting back all NIC's without IP addresses.
Inspection fails in this case.
This change makes inspection wait for *all* NIC's to get their IP addresses up
to a small timeout. The timeout is 60 seconds by default and can be changed
via the new ipa-inspection-dhcp-wait-timeout kernel option (0 to not wait).
After the wait inspection proceedes in any case, so the worst downside
is making inspection 60 seconds longer.
To avoid waiting for NIC's that are not even connected, this change extends the
NetworkInterface class with 'has_carrier' field.
