Support custom tolerations

[yteraoka]

Currently, this helm chart support only fixed toleration, but I want to add the custom tolerations to kuberhealty deployment.
So I added the .Values.deployment.tolerations.

Thanks

@yteraoka ignore my previous comment! but looks good to me! i think what would be useful is to comment out but add tolerations: under deployment values, similar to how there are args: and priorityClassName: just so folks know that is available!

@yteraoka / @joshulyne this will be a huge help for us too. Can't wait to see it merged!

@joshulyne I added blank tolerations into values.yaml as placeholder instead of comment.

@yteraoka thanks for adding that! I believe we're trying to avoid using blank properties so that they remain out of the spec and just commenting it out instead. We set a precedent for that in this pr: #635 and we're hoping to continue that! Sorry and thanks!!

@joshulyne I got it. I changed the blank variable to example comment. Thanks.
