Upgrade default raft version to 3 #157
Description
Raft protocol version 2 was deprecated in Nomad 1.3.0 and will be removed from version 1.4.0
It would be nice to have some default values up to date with this.
A solution could be to have the following defaults :
nomad_version < 1.3.0 use Raft 2
nomad_version >= 1.3.0 use Raft 3
