feat(circleci-plugin): incremental data collection (apache#7986)

* feat(api_collector_stateful): handle case were response has records from both before & after createdAfter of last collection

* feat(circleci-plugin): incremental collection for pipelines

* feat(api_collector_stateful): expose Input collector arg for StatefulFinalizableEntity to collect data based on previous collection

* feat(circleci-plugin): incremental data collection for workflows

* feat(circleci-plugin): incremental data collection for jobs

* refactor(circleci-plugin): use common query param function

* refactor(circleci-plugin): use BuildQueryParamsWithPageToken func when collecting unfinished job details
