* Support check_mode in ec2_vpc_nacl
Ensure that all API calls that make changes are guarded by
`if not module.check_mode`.
* Update ec2_vpc_nacl_facts to latest pep8 standards
* Add new helper function for comparing AWS tag key pair dicts. Also modify boto3_tag_list_to_ansible_dict function to be more generic when looking for key names because AWS sometimes uses 'Key', sometimes 'TagKey' and who knows what the future holds! Fixed modules to work with changes.
* Review changes
* Add some more doc to GUIDELINES for tags and fix var name for snaked values in ec2_group_facts
