Address KCLv3 issues from github (awslabs#1398)
Browse files Browse the repository at this point in the history
* Address KCLv3 issues reported on github
1. Fix transitive dependencies and add a maven plugin to catch these
   at build time
2. Remove the redundant shutdown of the leaseCoordinatorThreadPool
3. Fix typo THROUGHOUT_PUT_KBPS
4. Fix shutdown sequence - make sure
    scheduler shutdown without invoking run works
5. Fix backward compatibility check - Avoid flagging methods as deleted
    if it is marked synchronized. Also mark interfaces introduced in KCLv3 as internal.
