add API to read out the whole firmware configuration (including DPM layout)

customers request an API for their applications to read out the layout of the DPM. They want to know which IO-Devices submodule is located at which DPM offset.

An API shall be added to AP task that deliveres this information. The work flow needs to be defined. It seems appripriate to define services matching the configuration messages to read out the exact same datasets.
