Handle large number of files in a bucket, with a limit and filtering

[sergioleon3d]

Context: APS VScode Extension does not list the files in a buckets when the number of design files are really huge.

Proposal:
-> Limit the number of files listed in the bucket in the tree view to something that makes sense (100 items). Add at the end a note that indicates it only shows a limited number of files, and ask to use a filtering option to show more.
-> Allow to filter files inside a bucket by PREFIX, to show specific files inside a bucket with a huge amount of designs.

API (https://aps.autodesk.com/en/docs/data/v2/reference/http/buckets-:bucketKey-objects-GET/) allows to filter up to 100 and 'beginWith' parameters.

Thanks
