Description

Certain HDF5 files, when queried with Drill cause memory leaks due to the underlying C library. (See attached file)

This PR proposes to refactor the HDF5 plugin using a pure Java library (https://github.com/jamesmudd/jhdf) which will solve this issue. There should be minimal changes visible to the user.
