Design and implement database tables and associated DAO infrastructure code to manage DNP3 related settings:
- X.509 based authentication - issuer certificate(s), could be account-wide
- DNP3 Server - account-wide list
- X.509 subject DN - must be unique across ALL SolarNetwork, not just account
- List of data point mapping (node, source, property to DNP3 point, with possible data type and conversion settings)
- List of control point mapping (node, control, possible data type and conversion settings)
