Update curator api version to 2.x to 4.6.0

As the zookeeper version is updated to 3.5.x in Hive4-alpha
and the curator api version is updated to 4.x.
NoSuchMethodError occurs in the curator api included in the LLAP Tez tarball.
 

# hive4-alpha curator jar version

curator-client-4.2.0.jar
curator-framework-4.2.0.jar
curator-recipes-4.2.0.jar

# tez 0.10.1 curator jar version

curator-client-2.13.0.jar
curator-framework-2.13.0.jar
curator-recipes-2.13.0.jar

  It seems good to update the version of the curator api to match the Zookeeper 3.4.x version.
