Bug fix on ecs_service_facts.py

Hi all,
this is my first contribution on this list.

Some months ago i opened a bug ( https://github.com/ansible/ansible-modules-extras/issues/2437 ) on module ecs_service_facts about limited number of results to 10 even if a cluster have more services.

Locally i fixed this issue ( NextToken unmanaged on boto3 function “list_services” ).
Can i create a PR to share this fix or is already addressed?

Best,
Enrico
