Platform Login/Logout - fedml login/logout

Name	Default	Description
`--version` or `-v`	`release`	Login which backend environment version of TensorOpera AI Platform. It should be dev, test, or release.
`--computing` or `-c`	`true`	Login as the general compute node in TensorOpera AI compute network. This is enabled by default. After login, you can view and manage the device in the TensorOpera AI Platform: https://tensoropera.ai/compute. It can be grouped as a cluster and then you can use TensorOpera® Launch to schedule any job (training, deployment, federated learning) to it. You cannot specify options `-c` and `-s` simultaneously for a single environment.
`--server` or `-s`	`false`	Login as the FedML on-premise parameter server (PS). It can be used for PS-based training paradigms, such as distributed training, cross-cloud training, and federated-learning. You cannot specify options `-c` and `-s` simultaneously for a single environment.
`--provider` or `-p`	`false`	Login as the FedML compute node (GPU) provider (supplier). This is used by TensorOpera AI Platform - Share and Earn: https://tensoropera.ai/gpu-supplier. You can share your GPUs in this way and earn money. You can specify the option `-p` and `-c` simultaneously (can be used as provider for others as well compute node for your own jobs), but you can not specify `-p` and `-s` simultaneously.
