Add a deploy script to install/uninstall sample csi-driver

[Rakshith-R]

Is your feature request related to a problem?/Why is this needed

We need a deploy script that installs all the necessary resources to run external-snapshot-metadata sidecar with a csi-driver

Describe the solution you'd like in detail

A script that installs:

• snapshot CRDs
• snapshot controller
• generates certificates and create secrets
• install snapshotmetadataservice CRD and create its CR with required field
• deploys host-path csi-driver with required sidecars

Additional context

This would enable developers to quickly deploy and test their changes as well as for deployment in CI for
regular testing

Hey,
I am already working on updating deploy.sh script in csi-driver-host-path driver as a part of kubernetes-csi/csi-driver-host-path#569 to setup CSI driver with SnapshotMetadata service
