This PR includes a couple small fixes for wreck jobs with nokz.

  • #1899: fix flux-wreck attach with flux-wreckrun nokz jobs that are complete
  • Save output in kvs with flux-wreckrun for nokz jobs when --detach or --wait-until is used to avoid dropping all output.

wreck: don't run reactor for complete jobs in attach
Problem: flux-wreck attach for complete jobs with the "nokz"
option active will hang indefinitely, because there are no events
to wake up the mandatory call into the reactor.

Only call into the reactor for jobs that are not in the complete
state or having pending kz IO.

Fixes #1899
wreck: wreckrun: store output in kvs with nokz if -d or -w
Problem: wreckrun drops all output when run with --detach
or --wait-until when used with "nokz" and without --output and

As in flux-submit, default to kvs://files.{stdout,stderr} when
wreckrun is used with -o nokz and --detach or --wait-until.
