Changed resource_tags to tags to match other modules (resource_tags still an alias)

Added get_subnet_info method to return more subnet info - matches same method in ec2_vpc_subnet_facts module
Rework of tags - will now only apply the tags listed in the module.  Existing tags not listed will be removed (desired state!)
