CE side of ENT PR:
task schedule: pauses are not restart "attempts"
distinguish between these two cases:
1. task dies because we "paused" it (on purpose)
- should not count against restarts,
because nothing is wrong.
2. task dies because it didn't work right
- should count against restart attempts,
so users can address application issues.
with this, the restart{} block is back to its normal
behavior, so its documentation applies without caveat.
