      Description

      globStatus/globber is inefficient, not incremental and doesn't provide a way to query any IOStatistics.

      Proposed:

      • new IncrementalGlobber class which takes an interface to the file source (+impls for FS and FC) which offer the incremental ops
      • use incremental listStatusIncremental calls
      • or, if no wildcards, full deep listFiles(recursive)
      • collect IOStatistics from source ops, aggregate and serve

      Potentially a lot of work...need to look carefully here
