[Request Feature] Support Requester Pay Buckets in GCS FUSE CSI Driver

[shawnsavour]

Description:

Currently, the GCS FUSE CSI driver does not support buckets with Requester Pay enabled. This limitation prevents users from utilizing buckets where the requester is responsible for paying storage and network costs.

Proposed Solution:

To address this limitation, we propose adding a new volumeAttribute to the CSI driver configuration:

volumeAttributes:
  billingProject: <project-id>

By specifying the billingProject attribute, the CSI driver can be instructed to use the specified project's billing account for accessing the Requester Pay bucket.

Expected Behavior:

With this enhancement, the GCS FUSE CSI driver should be able to:

• Recognize Requester Pay Buckets: Identify buckets with Requester Pay enabled based on their bucket configuration.

• Use the Specified Billing Project: Utilize the billingProject attribute to authenticate requests to the bucket and charge costs to the correct project.
