HBASE-21317 [hbck2] Add version, version handling, and

misc override to assigns/unassigns

M hbase-hbck2/pom.xml
 Add handling of a hbck.properties file that gets bundle
 up in the jar. During build, interpolation adds version
 and git info via git-commit-id-plugin and filtering.

M hbase-hbck2/src/main/java/org/apache/hbase/HBCK2.java
 Add version emission. Add fail when we go against an hbase
 that does not support hbck2.

 Add assigns/unassigns override. Change 'force' on bypass
 to match. Add a recursive to bypass so if passed a parent
 it will find children and bypass them.
