[feature support] Enable to add affinities.

[monaka]

I want to set a Pod placement options in my multi-purpose K8s clusters. Especially, affinity:.

I created a patch against this issue. Could you accept and merge this ?

@monaka , I do not see issue with this. I don't think it will break anything. @kingdonb , thoughts?

If you make the PR, we can review and test it out. If it works for you with these changes it should work for all deployment type components.

@Cryptophobia Thanks for your review.
I wanna making PR based on this issue.
And, which repo should I send PRs for the workflow chart ?

[Cryptophobia]

@monaka , that is a good question. We need to make this as a PR to the workflow dir (but only update the values.yaml change and any of the umbrella chart helpers here). We also need to make a PR for each of the components chart/ directories. Since this is the umbrella chart we just pull all the children charts into here and compile this chart.

This is quite a bit of tedious work as it requires a PR into all the repos that have a chart with such deployment. We also need to add the affinity section to the values of each of the components value.yaml of their charts as well.

This can be scripted out for speed. For example, here is a script that can do this at a high level if you want to follow this: https://github.com/teamhephy/docker-base/blob/master/_scripts/make-prs.sh

The idea will be to do the same and only edit the *-deployment.yaml and values.yaml for each of those files in the chart/ directories.
