HBASE-25068 Pass WALFactory to Replication so it knows of all WALProviders, not just default/user-space 

Pass WALFactory to Replication instead of WALProvider. WALFactory has all
WALProviders in it, not just the user-space WALProvider. Do this so
ReplicationService has access to all WALProviders in the Server (To be
exploited by the follow-on patch in HBASE-25055)
