Updating status label colors to non-euca-green and non-euca-orange

@kamalgill I need your help getting the snapshot detail page to display the same status colors as the snapshot landing page, please. I can't figure out what to do with the snapshot.scss file since it doesn't seem to contain any status color definitions. 

I am also working on getting the thermometer to not use euca-green, will push that to this PR when I have it figured out.
