Adding license headers to the hbase-consensus module

Summary:
The hbase-consensus classes were missing apache license headers.
I am adding them.

Total files : 234
Licensed files : 232

Remaining two files :
1. IllegalArgument.java (Auto generated)
2. rmap.json (data for test cases)

java -jar apache-rat-0.11.jar --exclude 
./test/resources/org/apache/hadoop/hbase/consensus/rmap/rmap.json --dir ./

Test Plan: build and also run the rat tool
