Ensure chart env values are strings/quoted

[rjinski]

Trying to use KEEP_SECRET_NAME the values were interpolated as boolean.

values.yaml

env:
  KEEP_SECRET_NAME: "true"

Or helm template . --set "env.KEEP_SECRET_NAME=true"

Or helm_release terraform provider

resource "helm_release" "postgres_controller" {
 ...
  set {
    name  = "env.KEEP_SECRET_NAME"
    type  = "string"
    value = "true"
  }
  ...
}

Desired:

containers:
  env:
    - name: KEEP_SECRET_NAME
      value: "true"

Actual:

containers:
  env:
    - name: KEEP_SECRET_NAME
      value: true

json: cannot unmarshal bool into Go struct field EnvVar.spec.template.spec.containers.env.value of type string

Environment values must always be of type string

@rjinski as workaround

env:
  KEEP_SECRET_NAME: "'true'"

This is absolutely not hurtful but needed as the workaround is not that easy to find. It safe enough to be merged.

Nice work.
