Code review comment for lp:~radix/txaws/parameter-enrichment

I've fixed the 'rest' return format.

The only tests in landscape and clouddeck that are still failing are because of names in error messages.

I think this is a pretty tolerable incompatibility, but I'm going to see what I can do to do maintain compatibility here. Please take another look in the meantime (and if another reviewer wants to take a look, that'd be appreciated).
