Fix checkstyle for features submodules.
These are the remaining submodules that have checkstyle. Pretty clean compile after this. There were a couple of sonar fixes in there also. Issue-ID: POLICY-882 Change-Id: I8191ea1aa261f4a7b9d3d21c108572fd31db1b8c Signed-off-by: Pamela Dragosh <pdragosh@research.att.com>
