[master 2/2] lorax: Improve argument parsing and help

From: "Brian C. Lane" <bcl at redhat.com>
Make the metavars useful, not STRING. Simplify some of the error
checking, let the parser handle it. Add type=os.path.abspath to several
path arguments so that relative paths will be converted to absolute
paths when they are processed.
