Double-type search spaces should allow ranges including zero.

/kind feature

Describe the solution you'd like
It sould be nice if double type search spaces would allow ranges that overlap with zero. Currently this is problematic due to the log-uniform prior. A solution could be to make this prior configurable and to allow other options supported by skopt as well.

Anything else you would like to add:
