feat: support to disable private transaction managers

[solidnerd]

This is an implementation to support for none private transaction managers for generating all Kubernetes manifests

The current implementation allows both ways of support so you can set it explicit and implicit

Explicit would mean here:

  - Node_UserIdent: quorum-node1
    Key_Dir: key1
    quorum:
      quorum:
        # supported: (raft | istanbul)
        consensus: istanbul
        Quorum_Version: 2.6.0
      tm:
        # (tessera|constellation|none)
        Name: none
        Tm_Version: 0.10.4

And implicit

  - Node_UserIdent: quorum-node1
    Key_Dir: key1
    quorum:
      quorum:
        # supported: (raft | istanbul)
        consensus: istanbul
        Quorum_Version: 2.6.0
