Make the Options for Policy Library Sync to Be Consistent

On GCE, this is off by default, and needs policy_library_sync_enabled = true to be set.

On GKE, this is on by default, and policy_library_sync_enabled is not exposed to be configure-able.

Since there is a case for continued usage of GCS buckets, a couple of things need to be done:
1: policy_library_sync_enabled needs to be configure-able on GKE in case GCS is prefered
2: make consistent the default behavior whether it's on or off, on both GCE and GKE

This needs to be implemented with the corresponding Helm issue.

We will disable this feature on GKE by default in 2.23 release. If someone wants to use CV + Policy Library they can explicating enable this feature.

GCS sync support on GKE needs to be added. Our default out of the box behavior on GCE/GKE should be GCS Sync.
