Merging into dict from loop create new key

[robcxyz]

Related to #66, when merging into a dict from a loop, we should be creating new keys.

resources:
  name: operator
  type: helm
  do some merge->: literal {'foo-{{index}}':'foo-{{index}}'} --for [1,2,3] --merge

Now creates:

resources: 
  foo-2: foo-2

Which should be:

resources: 
  name: operator
  type: helm
  foo-0: foo-0
  foo-1: foo-1
  foo-2: foo-2

This is an edge case that practically has no purpose but should be accounted for.
