GCE support for G2 g2-standard-48 VM as wrapper of four L4 GPUs (CUDA CC 8.9 80G vram) via the LZ as raw headless GCE in addition to marketplace nvidia-rtx-virtual-workstation

add example workload config for G2 in general - for cuda/tensorflow/keras/llm training/inference

Alternate NVidia workstation deployment is already working via marketplace

## L4 GPUs per G2 VM
- https://cloud.google.com/compute/docs/gpus#l4-gpus
- 8 L4 per A2-standard-96 or 4 L4 per standard-48
- This requires the following additional quota requests (3)
- NVIDIA L4 GPUs from 4 to 8
- CPUs from 64 to 96 (includes CPUs (all regions)

```
| NAME | DIMENSIONS | REGION | REQUESTED LIMIT | APPROVED LIMIT |
+------------------+------------+--------+-----------------+----------------+
| CPUS_ALL_REGIONS | | GLOBAL | 96 | 96 |

```
- choose CUDA 12.1 over 11.8
