[SPARK-17473][SQL] fixing docker integration tests error due to different versions of jars.

## What changes were proposed in this pull request?
Docker tests are using older version  of jersey jars (1.19),  which was used in older releases of spark.  In 2.0 releases Spark was upgraded to use 2.x verison of Jersey. After  upgrade to new versions, docker tests  are  failing with AbstractMethodError.  Now that spark is upgraded  to 2.x jersey version, using of  shaded docker jars  may not be required any more.  Removed the exclusions/overrides of jersey related classes from pom file, and changed the docker-client to use regular jar instead of shaded one.

## How was this patch tested?

Tested  using existing  docker-integration-tests
