Fix #371.

[shivdudhani]

The above comment fixes issue #371, but have we handled all the policies and all resource types ?
If not let's add the fixes tag for this PR

[realshuting]

I went through policies in samples/best_practices, and tested with resource type Pod and Deployment. Since after #518, best practices would be applied to pod controllers by default.

Let test other polices too before closing the issue!

And the corresponding markdown files, if there are any updates.

Went through samples/more, we are all good, and docs are in sync.
