remove old 'searchqa' classes and files

these have been added in 2012 by Jeff
apparently, but it appears they are not
being used anymore with new search and were
largely unknown to current search people

popped up because it is one of the odd classes
only included on iron but not on all bastionhosts

delete the 2 classes, all files and from iron
