Our current method of CONNECT/DISCONNECT does not allow an NDEATH do be sent, as we are considered to be disconnecting gracefully.

Research must be done:
1. What are the Sparkplug B requirements for NBIRTH if we disconnect gracefully? disgracefully?
2. Can we disconnect disgracefully?
3. What are the requirements of our Testing IIoT Host Node, for NBIRTH / DBIRTH?
4. What can we do to recover from losing bdSeq synchronicity?

Part of this might mean we need to implement Node Control/Rebirth

    For MVP:
    user can no longer enable or disable the MQTT, it is just always on.
     implement "metrics":[{"name":"Node Control/Rebirth"}] to send a new birth certificate
