Description

WALEditCode needs to be pluggable to support alternative serialziation mechanisms.

The open question here is whether to support the alternative codec when doing replication - both clusters would need the codec on the classpath, which has additional overhead and also will be a little bit complicated when making the WAL serialization backwards compatible in 0.94.

This is the follow-up to HBASE-8636.
