Restrict clock skew adjustment to a certain max delta

[yurishkuro]

Similar to #961, perhaps we should impose a limit on the skew adjustment, e.g. no more than 1s. If the calculated delta exceeds that limit, add a span warning saying that adjustment was not done, and include the proposed delta in the message.

@yurishkuro I'd be glad to look at this:

Add a param to jaeger-query that takes a duration: --query.max-clock-skew-adjust

Internally default to a negative duration which would maintain current behavior.
Setting to 0 would disable all clock skew adjustment.

[yurishkuro]

I would default to something like 1sec, and use zero as "turn it off" equivalent.

Sounds good. I'll submit a PR in the next couple days.
