This is used by `bindep` [0] to assess if needed system packages are
installed.
It should allow easier installation of Python packages on a clean
system from source and help packagers too.
For now it is just a copy/merge of `devstack/files/[debs|rpms]/ironic`
files with added platform specifiers.
Packages have been tagged with certain bindep profiles:
- default - needed to run ironic service in production
- test - needed to compile Python dependencies and for other tox targets,
profile of this name is used by various gate jobs
- devstack - needed to setup VMs posing as HW nodes by the devstack
plugin
- imagebuild - only needed to build various types of deploy ramdisk
Note that DevStack install procedure currently does not use 'bindep',
and still relies on files in `devstack/files/...` folder.
