[SPARK-15095][SQL] drop binary mode in ThriftServer

## What changes were proposed in this pull request?

This PR drop the support for binary mode in ThriftServer, only HTTP mode is supported now, to reduce the maintain burden.

The code to support binary mode is still kept, just in case if we want it  in future.

## How was this patch tested?

Updated tests to use HTTP mode.
