ParallelTests::Tasks.suppress_output

this is a crazy-complex solution for a very simple problem:
removing certain lines from the output without changing the exit-status
normally I'd not do this, but it has been lots of fun and a great learning experience :)

- sed does not support | without -r
- grep changes 0 exitstatus to 1 if nothing matches
- sed changes 1 exitstatus to 0
- pipefail makes pipe fail with exitstatus of first failed command
- pipefail is not supported in (zsh)
- defining a new rake task like silence_schema would force users to load parallel_tests in test env
- do not use ' since run_in_parallel uses them to quote stuff
- simple system "set -o pipefail" returns nil even though set -o pipefail exists with 0
