Rework of sample timeout

[Amjcraft]

Context

Comes out of stoplightio/elements#2283
It appears ticks might not be a great indicator of time/performance. I think we need a followup ticket to rethink/rework this mechanism in the json schema sampler

Current Behavior

Expected Behavior

TBD. Lets discuss.

Possible Solution(s)

Move to a time based timeout
