Pull request for issue #157

Automatic change of nomad_raft_protocol during upgrade of nomad_version could crash the cluster.
The change require different upgrade steps - depending on Cluster with 1 or 3+ servers - before the server is started with new protocal version.
Single-Node won't start after changing the protocol version and you can't go back to previous version.

This could be mitigated by at least specifying the default for 1.4 to be protocol 3 as it's broken with protocol 2 anyway.
