Inline comments and helm template formatting

I think the suggested changes in this MR increase readability through more:

• inline comments
• more consistent white space chomping (almost always chomp left and not right)
• smart indentation using nindent and left-whitespace chomp instead of indent
• a more relevant inline comment example for envVars

I suggest reviewing of this PR is done commit by commit as they make some sense each of their own and have some comments with them.
