CRT readers communicate with socket writers via IOM

[denizergonul]

• For each connection, there are, per DataSender:
  • 1 dedicated D2D connection (with this sender only)
  • 1 CRT frame builder
  • 1 SocketWriter
  • 1 IOM
• CRT readers communicate with socket writers via IOM.
• Socket readers communicate with DHLs via callbacks.

To try out:

• create_config_plot -f config/daqsystemtest/example-configs.data.xml -r crt-data-source-01 -s local-socket-1x1-config

• create_config_plot -f config/daqsystemtest/example-configs.data.xml -r socket-ru-01 -s local-socket-1x1-config

I'll continue the conversation on this PR, though see #624 for the PR we should merge to the prep-release branch.

I think there's an issue with this line:

daqconf/python/daqconf/generate.py

Line 736 in f1e0c4c

callback_desc=cb_desc,

When I try to run the readout_type_scan.py integration test, I get errors like:

I haven't fully tracked this down, but I think with the recent changes there is no callback descriptor that is being used for the CRT Bern and CRT Grenoble cases, where it is still instantiating a readout application in the readout type scan.
