The fix for CLOUD-427 introduced truncation of the "jboss.node.name" to last 23 characters (that's the length specified in the XA specification and cannot be changed).

That fix is however suboptimal:

• since the node no longer knows its identity. That's required in order for the application server to set affinity of the session that is e.g. mandated by hash function when using Infinispan distribution mode
• it's plain confusing to users and debugging since the node name does not correspond to the pod name and needs to be inferred.

To fix this simply we need to introduce and replace by tx specific e.g. JBOSS_TX_NODE_ID property and pass both.
