Added method to VolumeManager that accepts a collection of Paths to delete. If the underlying FileSystem supports bulk deletion, then that API method is called. Otherwise the Paths are deleted using an ExecutorService.

Reviewed the existing code that used the other delete methods in the VolumeManager. Only two places seemed like candidates for using the new deleteBulk method. The other locations either only deleted one file aperiodically, or deleted many files but using some complex logic. The former didn't make sense to modify and the latter could potentially be modified later with some refactoring.

Closes #5131
