Implement a POC for filtering data to be cloned via the storage execution layer on the source side rather than the query layer for resharding

• • Create a filter for target documents and add ranges for index keys (most of this is done in POC)
  • Allow specifying this filter for queries (find)
    • Cursors already have a show recordID option
  • Filtering for record store
  • Filtering for sorted data interface
  • Test queries for both collection data and index data
  • Filter at a point in time

Action Item:

• • Dust off skunkworks POC and get familiar with the implementation*

• • Squash commits and merge into fork of master*
