Added a DAQ session overall time measurement to the integrationtest results…

…that are passed back to users so that it can be used for fine-tuning ranges in various time-based checks on the results of the test.

Description

This PR is correlated with a PR in the daqsystemtest repo, specifically DUNE-DAQ/daqsystemtest#276.

The changes in this repo are rather straightforward: measuring the overall wallclock time that is spent running the DAQ session and passing that value back to the user in the RunResults structure.

This change was prompted by a recent failure in the number-of-metric-samples validation check in daqsystemtest/minimal_system_quick_test.sh. Instead of an expected 3 metric samples in that test, 6 metric samples were observed. The extra samples were caused by a longer-than-normal run time of the DAQ session. (I'm not sure which DAQ transition took longer than normal, nor why that may have happened.)

Here are suggestions for testing these changes in conjunction with the ones in daqsystemtest:

TIME_SUFFIX=`date '+%H%M'`

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 (daqsystemtest_integtest_bundle.sh)

Further checks

• Code is commented where needed, particularly in hard-to-understand areas
