  ## Problem it solves
  
  I'm always frustrated when I have to scroll my screen up every time when the response is long. In some testcase(s) I'm interesting in a specific json key(s) and response header but some of the key(s) has really looong content and I don't care of it.

  ## Additional information, screenshots, or code examples
  
  It would be nice to have an option `--filter-keys foo,bar.boo` which will remove those keys from response before it will be well formatted.
