Undocumented options in '--help' for 'sam package'

Description

The sam package command doesn’t document the --output-template-file in the options list. It does use it in the example, but them leaves it out of the documented options.

Also suggest it should document the --s3-prefix option.

Steps to reproduce

sam package --help

Observed result

Usage: sam package [OPTIONS] [ARGS]...

  The SAM package command creates a zip of your code and dependencies and
  uploads it to S3. The command returns a copy of your template, replacing
  references to local artifacts with the S3 location where the command
  uploaded the artifacts.

  e.g. sam package --template-file template.yaml  --output-template-file packaged.yaml
  --s3-bucket REPLACE_THIS_WITH_YOUR_S3_BUCKET_NAME

  This is an alias for aws cloudformation package. To learn about other parameters you can use,
  run aws cloudformation package help.

Options:
  --template-file PATH  The path where your AWS SAM template is located
  --s3-bucket TEXT      The name of the S3 bucket where this command uploads
                        the artifacts that are referenced in your template.
                        [required]
  --debug               Turn on debug logging to print debug message generated
                        by SAM CLI.
  --help                Show this message and exit.

Expected result

Expected --output-template-file option to be documented under ‘Options’. And suggest the --s3-prefix option should be there too.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Windows 10
2. sam --version: SAM CLI, version 0.18.0

We have recently removed our reliance on aws cli for sam package. Starting in v0.31.0, all options are present in the help text. We are still working through deploy.

Given this issue is about package, I am going to close this one.

This will be addressed with #1437.

sam package shells out to aws cloudformation package in AWS CLI. Any option your installed AWS CLI version supports is supported by sam package. Which is also mentioned in the help text: “This is an alias for aws cloudformation package. To learn about other parameters you can use, run aws cloudformation package help.”
