Draft: Support log-uniform scale in search space definition

[fabianvdW]

Hello everyone,

I would like to see some movement in #1207. I started by adding the distribution field everywhere I could find and already modifying the behaviour in the suggestion package at relevant places.

I am guessing this PR is not even close to finished. Maybe someone can point out to me which parts are still missing(and or have to be adapated), or discuss if my approach to fixing #1207 is good. Perhaps one of the main contributors can also take over from here.
What this PR does / why we need it:
This adds a field distribution to SearchSpace which allows for the "log-uniform" scale (and possibly other scales) to be supported for sampling from parameter search spaces.

Fixes #1207

Hi @fabianvdW. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
