Hector Sanjuan 59714f69d4 Allow running peers with different cluster versions in the same cluster
This patch modifies the RPC protocol tag to use Major and Minor parts of the
version and not all of it.

This means all peers on the 0.5.x can run in the same cluster.

As cluster has become more mature and I see less risks in letting peers from
similar versions run together. This is useful when upgrading too.
