* 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
* Add ability to use either sec group name or sec group id or combination to ec2_lc. Also fix header size in AWS Guidelines
* Fix ec2 import to only import neccessary packages. Remove pep8 double line
