Error parsing bastion yaml

[alok87]

This PR #694 introduced private networking. After this PR, on doing below tasks to setup a new cluster with private networking i get the parsing error shown below.

• kops create cluster --networking cni --topology private --zones=us-west-1a uswest1.clusters.mydomainexample.com
• kops edit cluster uswest1.clusters.mydomainexample.com
• added bypassBastion: true under topology and :wq
• kops update cluster uswest1.clusters.mydomainexample.com --yes

The last update command fails with the below error

@kris-nova: The error gets resolved on removing the comments from bastion.yaml. Can u verify?
