0.17.0

• Added a new reindex command which will go through all tables on a cluster
  which need to be re-indexed to be compatible with CrateDB major_version+1. It
  will one by one create a copy of a table and then remove the old table,
  replacing it with the copy.

• Added a new infile argument to the insert-json command. This should
  make certain scripting scenarios easier.
