docker stack deploy help is missing orchestration specific flags

[sudo-bmitch]

Description

The help message for docker stack deploy --help does not include orchestrator specific options.

Steps to reproduce the issue:

Run any of:

• docker stack deploy --help
• docker stack deploy --orchestrator swarm --help
• docker stack --orchestrator swarm deploy --help

Describe the results you received:

The output only includes the common options:

$ docker stack deploy --help

Usage:  docker stack deploy [OPTIONS] STACK

Deploy a new stack or update an existing stack

Aliases:
  deploy, up

Options:
  -c, --compose-file strings   Path to a Compose file
      --orchestrator string    Orchestrator to use (swarm|kubernetes|all)

Describe the results you expected:

The output should include all options, or at least the swarm specific options when run with that orchestrator flag, e.g. here's the output from a prior version (note the --prune, --resolve-image and --with-registry-auth options):

$ docker stack deploy --help

Usage:  docker stack deploy [OPTIONS] STACK

Deploy a new stack or update an existing stack

Aliases:
  deploy, up

Options:
      --bundle-file string     Path to a Distributed Application Bundle file
  -c, --compose-file strings   Path to a Compose file
      --prune                  Prune services that are no longer referenced
      --resolve-image string   Query the registry to resolve image digest and supported platforms ("always"|"changed"|"never") (default "always")
      --with-registry-auth     Send registry authentication details to Swarm agents
