[gargnitingoogle]

Description

Handle dependencies for successful execution on a GCE VM.

• Install google-cloud-monitoring python package
• Wait 30 min after CSI driver installation, before deploying pods, to avoid failure
• Avoid putting google in the name of the package-bucket as google is not allowed in bucket names.
