  Creates a new KeyHandle, triggering the provisioning of a new CryptoKey for
  CMEK use with the given resource type in the configured key project and the
  same location

  ## EXAMPLES

  The following command creates a KeyHandle named `my-key-handle` within the
  location `global` for the resource type `compute.googleapis.com/Disk`:

    $ {command} --key-handle-id=my-key-handle --location=global
    --resource-type=compute.googleapis.com/Disk

  To generate a random KeyHandle id, the `--generate-key-handle-id` flag can be
  used instead of `--key-handle-id`.
