Add bare-pods and hostpath-volume to doks group

[varshavaradarajan]

• Checks is doks group are run by default on DOKS

doks group now has:

• bare-pods,
• hostpath-volume,
• node-labels-and-taints
• admission-controller-webhook
• node-name-pod-selector

@adamwg - we didn't discuss node-name-pod-selector as part of the checks run during upgrade on DOKS. But, I think it should be there, similar to node-labels-and-taints. Even though it doesn't generate an error that would break upgrade, upgrade affects workloads that these checks identify.
