    Suppress pyflakes issues by prefix or suffix
    
    On #17306 neel's test output has quite a few pyflakes issues I don't get...
    
      https://trac.torproject.org/projects/tor/attachment/ticket/17306/integ_test.txt
    
    These would be a hassle to suppress one by one so allowing our config to
    suppress by prefix or suffix.
