Add support for all the new single VM compute-envs

[robnewman]

The tw-cli doesn't support any of the new single VM CEs (AWS Cloud, Google Cloud, Azure Cloud):

tw compute-envs add -h

Usage: tw compute-envs add [OPTIONS] [COMMAND]

Add new compute environment.

Options:
  -h, --help      Show this help message and exit.
  -V, --version   Print version information and exit.

Commands:
  k8s             Add new Kubernetes compute environment.
  aws-batch       Add new AWS Batch compute environment.
  eks             Add new Amazon EKS compute environment.
  slurm           Add new Slurm compute environment.
  lsf             Add new IBM LSF compute environment.
  uge             Add new UNIVA grid engine compute environment.
  altair          Add new Altair PBS Pro compute environment.
  moab            Add new MOAB compute environment.
  gke             Add new Google GKE compute environment.
  google-ls       Add new Google life sciences compute environment.
  google-batch    Add new Google Batch compute environment.
  azure-batch     Add new Azure Batch compute environments.
  seqera-compute  Add new Seqera Compute environment.

If we're recommending our users provision these for pipelines and studio sessions, we need to support them via the CLI and ultimately seqerakit too.

Also, Google Life Sciences (google-ls) has been deprecated in Seqera Platform and should be removed from the list of available compute environments.
