Comment 13 for bug 48070

As discussed with pitti, I will change the way the command line works for using "override".

Instead of:
    queue override <filter> [override_stanza*]

    Where override_stanza is one of:
    source [<component>]/[<section>]
    binary [<component>]/[<section>]/[<priority>]

I will change this so that there are command line options instead:
-c or --component
-x or --section
-p or --priority
and change the order of the <filter> and <source/binary> stanza.

This does two things:
1. Makes it consistent with change-override.py
2. Makes it possible to process multiple overrides as per the bug requirement.

example:
queue override -c universe source 5 10 667
