Subject: [PATCH] Exclude jline from transitive dependencies of hadoop

jline was being pulled in transitively via hadoop-yarn-client, which is
used by several hadoop dependencies (hadoop-common, hadoop-client,
hadoop-mapreduce-client-core).

This CL excludes jline from hadoop-yarn-client in dependencyManagement in
the root pom.xml to prevent it from being included.
Verified that jline is no longer in the dependency tree and that unit
tests in v1 (classic-templates) and v2/common pass.
