Description

This task aim to ideliver a new Quorum Vote mechanism for artemis with the objectives:

1. to make it pluggable
2. to cleanly separate the election phase and the cluster member states
3. to simplify most common setups in both amount of configuration and requirements (eg "witness" nodes could be implemented to support single master-slave pairs)

Post-actions to help people adopt it, but need to be thought upfront:

1. a clean upgrade path for current HA replication users
2. deprecate or integrate the current HA replication into the new version
