Feature: Support complex values

[jkroepke]

Current Behavior

When I have the following template:

apiVersion: v1
kind: Secret
metadata:
  name: test
stringData: ref+awsssm://test

With a value in Parameter Store in YAML format:

value1: secret
value2: secret

I get the following rendered secret:

apiVersion: v1
kind: Secret
metadata:
  name: test
stringData: |-
  value1: secret
  value2: secret

I would like to give vals an hint that the value should be not handle as string, instead it just be insert as object into the existing yaml structure.

for example:

apiVersion: v1
kind: Secret
metadata:
  name: test
stringData:
  value1: secret
  value2: secret
