Incorrect enforcement of request.imp.metric

[naegelin]

PBS is rejecting metrics with a float value greater than 1.0 . Per openrtb 2.6 specifications, this value must ONLY be in the range of 0.0 to 1.0 if the metrics are probabilities, otherwise normal Float values should be accepted.

throw new ValidationException("%s.metric[%d].value must be in the range [0.0, 1.0]", msgPrefix, i);

@Net-burst to look into this.

I lost track of this issue, but it seems to be a valid one. I can't find any source that would imply that there is a limit on a value. I'm promoting this issue to Ready for Dev.
