Attach production queue volume (xdmod-prod-queue-vol-$BUILD_DATE) to staging instance $instance_id at /dev/vdc.

This commit optimizes the process of detaching and removing staging volumes from the staging instance. It replaces the previous approach of using a single staging volume with a new approach that involves two distinct volumes. 

The original code assumed only one volume is attached to the specified OpenStack instance. This commit modifies the script to correctly handle scenarios where multiple volumes are attached. The updated code uses an array to store all attached volumes, iterates over the array, and performs actions for each volume. This enhances the script's flexibility and ensures accurate detachment messages for all attached volumes.

Changes:
- Modified the extraction of the instance ID to handle potential changes in the output structure.
- Implemented an array to store all attached volumes.
- Added a loop to iterate over the array and print detachment messages for each volume.

- Added a new data block storage resource in Terraform configuration.
- Updated the remote-exec provisioner to mount the XDMod queue data volume.
