Full refactor

* find running digests also in k8s (also: `check_eks`, `check_ecs` flags)
* add loads of logging (instead of print)
* rename `ignore_tags_regex` to `protect_tags_regex` and address awslabs#34
* set ecs_client Config params (connect_timeout, read_timeout, max_attempts)
* add `repo_name_regex`
* add `protect_latest` flag
* add `older_than` filter inspired by awslabs#18
