Checklist:

• I've searched in the docs and FAQ for my answer: http://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

• I used argocd by using remote build of kustomize, but a warning has come out from v1.5.0.
  I didn't see it in v1.4.2.

2020/04/03 19:47:55 nil value at `env.valueFrom.configMapKeyRef.name` ignored in mutation attempt
2020/04/03 19:47:55 nil value at `env.valueFrom.secretKeyRef.name` ignored in mutation attempt

To Reproduce

• Do kustomize build with remote build.

Expected behavior

Version

• argocd v1.5.0

• kustomize 3.5.4

• Run kubeval to make the results more understood.
