[ice] first stab at enabling resource listing (our role will be primary)

From the Ice wiki:

To use the breakdown feature and application group feature, first make sure you signed up the beta version of detailed billing file with resources and tag. 

It appears that enabling tags halfway through the month causes confusion in Ice with the untagged lines, so we'll have to really take a look at this starting in August.  I tried adjusting the processing start date to July 11 (I turned on tags on the 10th), but Ice then just ignores the entirety of the files in June and July.
