[SPARK-15004][SQL] Remove zookeeper service discovery code in thrift-server

## What changes were proposed in this pull request?
We recently inlined Hive's thrift server code in SPARK-15004. This patch removes the code related to zookeeper service discovery, Tez, and Hive on Spark, since they are irrelevant.

## How was this patch tested?
N/A - removing dead code

Author: Reynold Xin <rxin@databricks.com>

Closes #12780 from rxin/SPARK-15004.
