Use (if possible) configured timeout for restart

If Test Result is associated with Test Node and thus distributor, and
distributor defines process timeout use this timeout to now when to
restart test lines. This is useful to avoid needless restart of tests
running on nodes related to long time outing distributors.

Otherwise fallback to default.
