Add a funcutils file for working with functions.

Multiple projects are starting to copy around the various
function utilities that exist in nova and elsewhere. It
would seem appropriate that there exist a helper file in
oslo that was used instead as a central place for this type
of code.

Handle relative path arguments in Killfilter

KillFilter currently expects an absolute path
to be specified for the process name to kill. This
is inconvenient when the exact location of the running
binary is not known or differs accross installs.

Extend KillFilter to accept also commands in $PATH
to be killed if the given argument is not absolute.
