stack updated HBASE-17442:
    Attachment: 0001-hbase-replication-module.patch

Here is a first cut at a replication module. Does the module and then tries to 
move one utility class. Currently not compiling because the moved class is 
needed by hbase-server.

Moving replication out of hbase-server will be an involved task. Replication is 
too tightly wound up in the hbase-server core. Replication classes are also 
exposed in hbase-client. Replication classes don't seem to do Interfaces so 
tough having implementation distinct from definition. I could spend a bit more 
time on it but as of this writing, it seems like a large undertaking.... 

I notice that you are doing a bunch of work moving the replication changes to 
go via Master [~zghaobac]. This is a great project. Maybe come back to this 
task of moving out to hbase-replication after this refactor is done? After more 
experience with Replication layout?
