Inconsistent CLI parameters to specify resources requests and limits across training and inference

For training, the CLI parameters are:

```
--accelerators INTEGER Number of accelerators (GPUs/TPUs)
--vcpu TEXT Number of vCPUs
--memory TEXT Amount of memory in GiB
--accelerators-limit INTEGER Limit for the number of accelerators (GPUs/TPUs)
--vcpu-limit TEXT Limit for the number of vCPUs
--memory-limit TEXT Limit for the amount of memory in GiB
```

For inference (custom endpoints), the CLI parameters are:

```
--resources-requests JSON JSON object of resource requests, e.g. '{"cpu":"1","memory":"2Gi"}'
--resources-limits JSON JSON object of resource limits, e.g. '{"cpu":"2","memory":"4Gi"}'
```

Also, as mentioned in issue 306 (https://github.com/aws/sagemaker-hyperpod-cli/issues/306), the CLI should offer a consistent way to specify EFA (and Neuron) devices.
