Enable awsvpc network mode for ECS services and tasks and
their underlying task definitions
Improve test suite to thoroughly test the changes
Use runme.sh technique to run old and new versions of botocore to
ensure that the modules work with older botocore and older network modes
and fail gracefully if awsvpc network mode is used with older botocore
* Mark UCS integration tests as unsupported.
* Mark various connection tests as unsupported.
* Mark win_domain_group test as unsupported.
* Mark java_cert test as unsupported.
* Mark synchronize-buildah test as unsupported.
* Mark various AWS tests as unsupported.
* Mark azure_rm_acs test as unsupported.
* Mark GCP tests as unsupported.
* Use AnsibleAWSModule to simplify AWS connection
* Add Exception handling, pagination, retries and backoff
* Allow events to be switched off
* Allow details to be obtained without having to specify services
ecs_taskdefinition_facts should not populate ansible_facts with
so much information.
Better to just return the contents of the dict directly.
Reduce line lengths, use AnsibleAWSModule, don't reimplement
camel_dict_to_snake_dict.
Tests for:
* ecs_cluster
* ecs_service
* ecs_service_facts
* ecs_taskdefinition
* ecs_taskdefinition_facts
* Add idempotency testing
Test ecs_cluster, ecs_service and ecs_taskdefinition for trivial
idempotency. Add FIXMEs to the tests because the latter two fail.
Remove unused dependencies
