* Improve PEP8 compatibility
* Fix Python 3 incompatibility
Is prohibited to mutate OrderedDict during iteration through it so
is better to add records with error or warning to empty dictionary
instead of delete records from copy of dictionary during iterating.
* Decode output of subprocess from bytes to unicode.
* Add Python 3 support for validate-modules test.
Fix#18367
Made ansible-doc more plugin agnostic
We can have docs in lookup, callback, connectionm strategy, etc
Use first docstring and make pepizis happy
generalized module_docs to plugin_docs
documented cartesian, ssh, default, jsonfile, etc as examples
changed lack of docs to warning when listing
made smarter about bad docstrings
better blacklisting
added handling of options/config/envs/etc
move blacklist to find_plugins, only need once

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.
* Fix string formatting
* Provide better tracebacks
* When options is None and extends_documentation_fragment is in use, add an error that options must be a dict
* If options was specified and not a dict, then error
* Re-enable module comparisons, specifically for new module detection and for finding new options/arguments
* Only do new module checks in shippable, local will display warning
* Update validate-modules
* Validates ANSIBLE_METADATA
* Ensures imports happen after documentation vars
* Some pep8 cleanup
* Clean up some left over unneeded code
* Update modules for new module guidelines and validate-modules checks
* Update imports for ec2_vpc_route_table and ec2_vpc_nat_gateway
Print out the data that fails to validate when doing
schema checking on modules
This allows easier interpretation of error messages.
From:
```
ERROR: DOCUMENTATION.notes.2: expected basestring
```
To:
```
ERROR: DOCUMENTATION.notes.2: expected basestring @ data['notes'][2].
Got {"As with C(include) this task can be static or dynamic, If static
it implies that it won't need templating nor loops nor conditionals and
will show included tasks in the --list options. Ansible will try to
autodetect what is needed, but you can set `static": 'yes|no` at task
level to control this.'}
```
This allows validate-modules to run in an environment where
python 3 is the default. This will no longer be necessary once
validate-modules is updated to work with both python 2 and 3.
