[SPARK-14721][SQL] Remove HiveContext (part 2) ## What changes were proposed in this pull request? This removes the class `HiveContext` itself along with all code usages associated with it. The bulk of the work was already done in #12485. This is mainly just code cleanup and actually removing the class. Note: A couple of things will break after this patch. These will be fixed separately. - the python HiveContext - all the documentation / comments referencing HiveContext - there will be no more HiveContext in the REPL (fixed by #12589) ## How was this patch tested? No change in functionality. Author: Andrew Or <and...@databricks.com> Closes #12585 from andrewor14/delete-hive-context.
