gcp_compute_region_disk ignores source_snapshot parameter

[Dadavan]

SUMMARY

When using the gcp_compute_region_disk module with the source_snapshot parameter, the parameter is ignored and an empty disk is created.
I believe this is due to the absence of source_snapshot from this modules resource_to_request function:

google.cloud/plugins/modules/gcp_compute_region_disk.py

Line 508 in eec40d5

def resource_to_request(module):

See the gcp_compute_disk module, which does work:

google.cloud/plugins/modules/gcp_compute_disk.py

Line 665 in eec40d5

u'sourceSnapshot': replace_resource_dict(module.params.get(u'source_snapshot', {}), 'selfLink'),

STEPS TO REPRODUCE

Create a disk using the following snippet.
Inspect the created disk and see that it has no source snapshot.

  - name: Create disk
    gcp_compute_region_disk:
      project: my-project
      name: my-disk
      source_snapshot:
        selfLink: "{{ data_disk_snapshot.resources[0].selfLink }}"
      region: europe-north1
      replica_zones:
      - europe-north1-a
      - europe-north1-b

EXPECTED RESULTS

A disk should be created from the specified source snapshot.

ACTUAL RESULTS

An empty disk was created, the source_snapshot parameter is not present in the GCP resource spec.
