[Bug]: extraObjects accepts only string as templates

[oncipriani]

What happened?

I tried to use the "extraObjects" to create a Pod Disruption Budget object, but I could not find any way to add the proper labels, because apparently all templated values inside the "extraObjects" list must be quoted. That means that only simple string literals can be generated by the templates.

Even the example extrObject provided in the documentation does not work.

See #240 for more details.

Steps to reproduce

1. Create a values.yml with at least one extraObject element containing at least one non-quoted template;
2. Try to render the chart using helm template.

Expected behavior

The chart renders correctly, including the extra objects provided.
