CRT topology change

[denizergonul]

CRTReaderApplication creates:

• 1 CRT(Bern/Grenoble)Reader per SocketDetectorToDaqConnection
• 1 SocketWriter per SocketDetectorToDaqConnection
  CRTReader has N callback confs, where N is the number of streams in its connection.
  SocketWriter has the same N callback confs.

Prior to this development, socket connection info resided in reader and writer configurations. Now, there is SocketDetectorToDaqConnection which has SocketDataSenders and SocketReceiver; SocketDataSender has the info socket type (TCP/UDP), local port and remote port; plus we make use of their NetworkInterface.ip_address to interpret them as local IP and remote IP.

This diagram shows the relationships between configuration objects and modules. Here, SocketDetectorToDaqConnection1 represents socket_crt in the example config in daqsystemtest.

CRT readers communicate with socket writers via callbacks.
Socket readers communicate with DHLs via callbacks.

To try out:

• drunc-unified-shell ssh-standalone config/daqsystemtest/example-configs.data.xml local-socket-1x1-config ${USER}-local-test
• Reverting DUNE-DAQ/daqsystemtest@8d9a006 then generate_modules_test local-socket-1x1-config crt-data-source-01 config/daqsystemtest/example-configs.data.xml
• generate_modules_test local-socket-1x1-config socket-ru-01 config/daqsystemtest/example-configs.data.xml

Type of change

• New feature or enhancement (non-breaking change which adds functionality)

Testing checklist

• Minimal system quicktest passes (pytest -s minimal_system_quick_test.py)
• Full set of integration tests pass (dunedaq_integtest_bundle.sh)

Further checks

• Code is commented where needed, particularly in hard-to-understand areas
• Code style is correct (dbt-build --lint, and/or see https://dune-daq-sw.readthedocs.io/en/latest/packages/styleguide/)
