[HBASE-18723] [pom cleanup] Do a pass with dependency:analyze; remove unused and explicity list the dependencies we exploit

• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Fix Version/s: 2.0.0-alpha-3, 2.0.0
• Component/s: pom
• Hadoop Flags: Reviewed

Release Note

Purged a bunch of dependencies included but unused. Added reference to dependencies we do use but did not list (transitively included). Purged all but junit from parent pom dependency set and did explicit include in modules instead; not all modules need mockito, etc. Still work to do: grey area around hadoop and its transitive includes need cleanup still to make the dependency:analyze runs clean. Also figure how to purge junit from parent dependency list.

Description

Do a pass over our poms. They are sloppy including unused jars and not listing actually used dependencies. Undo 'required' dependencies like junit and mockito; not all modules need these anymore.

This cleanup motivated by failures up on jenkins where a build step is not finding transitive includes; explicit mention is needed (See failures in HBASE-18674).
