For the details about argcomplete, Please refer to

https://github.com/kislyuk/argcomplete
With this patchset, Users can use completion in bash.
ex:
$ virt-xml --<TAB><TAB>
$ virt-install --disk <TAB><TAB>
$ virt-install --panic model=isa,<TAB><TAB>
$ virt-install --controller model=virtio-scsi,ty<TAB><TAB>

Okay I haven't looked to deeply into this format here, kinda looks like
black magic :)
But does this launch each tool for each completion attempt? Might
explain why the completion is pretty slow in my testing. I don't want to
maintain 4 files but maybe we could use sed to splice in the tool name
at setup.py build time. Would also allow simplifying the setup.py
process a bit. I'd be happy to fix these bits after the initial series
though
Thanks,
Cole
