Annie Lezil fdcb0922a5 Collect NIC name given by BIOS 
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.

Closes-Bug: #1635351
