new dell-dup package posted

[Michael_E_Brown at Dell.com]

I have posted a new version of dell-dup to the repository. This version has several enhancements. For everybody who was hitting the previous traceback error, please test with this new version and report back.

Enhancements:
-- Speed: caches inventory from the inventory collector across calls for huge speed improvement
-- fault tolerance: should no longer crash on errors from the inventory collector
-- disabled inventory from Dell DUPs: This is a two-edged sword. We get huge speed improvements by not running multiple dup inventory modules, but we also now require dell_inventory_collector or DUPs cannot be used.
