John R Barker 04e816e13b Stricter module documentation validation (#22353)
Raise the bar for module `DOCUMENTAION`
This validator update was used to find the issues in https://github.com/ansible/ansible/pull/22297/files

**Validation**
* Updated Validation and docs to enforce more (items fixed in https://github.com/ansible/ansible/pull/22297/files)
* Use `suboptions` to document complex options 
* Validate module name
* Validate deprecated modules have correct ANSIBLE_METADATA

**Module Documentation Generation**
* Document `suboptions:` Example https://gist.github.com/gundalow/4bdc3669d696268328ccc18528cc6718
* Tidy up HTML generation (valid HTML, no empty lists, etc)
 
**Documentation**
* Clarify the steps for deprecating a module
* Use correct RST headings
* Document `suboptions:` (options)
* Document `contains:` (returns)


**Details**
The aim is to get this (and corresponding module updates) complete by the time `devel` becomes `2.4`, as this allows us to raise the bar for new modules

Example `suboptions` https://gist.github.com/gundalow/4bdc3669d696268328ccc18528cc6718

The aim is to get this PR integrated into `devel` *before* we branch `stable-2.3`, this will allows us to:
* Raise the bar for new modules in 2.4
* Ensure the generated module documentation for 2.3 and higher is improved, important as we will be doing versioned docs moving forward.

# Things to add soon
####################
# 1) Validate RETURN, including `contains` if `type: complex`
# This will improve documentation, though require fair amount of module tidyup
# Possible Future Enhancements
##############################
# 1) Don't allow empty options for choices, aliases, etc
# 2) If type: bool ensure choices isn't set - perhaps use Exclusive
# 3) both version_added should be quoted floats
# 4) Use Recursive Schema: https://github.com/alecthomas/voluptuous/issues/128 though don't allow two layers
# Tool that takes JSON and generates RETURN skeleton (needs to support complex structures)
