"""Allows fetching of items in batches (pages)
Workflow:
1. Determine the total number of items that we need to fetch based on the ``len`` parameter (If not specified,
assume infinite and fetch until ControlHub returns results).
2. Use the len(self) (which calls :py:meth:`streamsets.sdk.sch_api.ApiClient.get_pipelines_count`) as a source
of truth for the total number of pipelines existing in the ControlHub pipeline repository.
3. Keep incrementing the offset with ``PAGE_LENGTH`` and query with new offset and ``PAGE_LENGTH`` until we
reach requested number of items or we don't get any more items from ControlHub.
4. While fetching these items in a loop, it is possible that some of the items are deleted by someone else
affecting the current offset we are using. To handle this, in the while loop, if the len(self) decreases, we
reduce the current offset by the number of items decreased (making sure, we aren't missing any items).
5. In the list of items (order in which ControlHub returns the items), if the items that we already
queried are deleted, the actual offset we have to use would reduce by the number of items deleted.
On the otherhand, if
the items that are deleted are the ones we haven't fetched yet, then we have reduced the offset which is not
needed and hence end up getting duplicates. To handle this, we use a set to store all the item ids and
yield only the one's we haven't fetched yet.
eg. Lets say there are 59 pipelines in ControlHub and the parameter len is not specified.
After we fetch the first 50 pipelines, if index 48, 49 and 50 pipelines are deleted,
the sch fetch would miss the new 48th and
49th pipelines since the offset we would be using would be wrong. To handle this, we will reduce the sch
offset from 50 to 47 which would mean we would be fetching the 47th pipeline again and we handle this using
the all_ids set but we won't be missing the new 48th and 49th index pipelines (old 50 and 51).
