Add a `recursive` option to the git command.

Make it possible to clone without submodules by setting
recursive to no. Default is yes, so no change is needed
in existing plays.
Introduce module layman
add registry option to npm module
Added subnet tagging.
Added documentation for subnets: tags: option
Refactored subnet tagging to account for AWS delays; added 'tags' attribute to 'subnet' node in the returned json.
Renamed subnet's 'tags' attribute into 'instance_tags' to distinguish it from Ansible's own 'tags' and to conform to ec2 module naming for AWS tags.
Renamed instance_tags to resource_tags based on community feedback.
Add rollbar_deployment module
