Prevent client from reload()-ing CMSSW configs

CMSSW configs don't like to be imported multiple times in the same
process. The better solution would be to fork() out the part that
handles the configuration handling, but in the short-term, this commit
takes care of the "easy" case
Merge branch 'bugfix/dont_import_multiple_times' into feature/changes_for_api
Make the client not print any output if requested

Previously client would dump short status even if requested otherwise
