…that are part of the --integtest-verbosity changes.

These changes are intended for the fddaq-v5.7.0 software release.

Description

In discussions of possible improvements to our regression/integration tests, it was suggested to provide several different levels of verbosity. These changes are part of implementing those, and this PR is best tested and merged with DUNE-DAQ/integrationtest#152. The integrationtest PR has some details about the changes.

The iceberg_real_hsi_test is not currently fully operational, but these changes were an attempt to keep it somewhat up-to-date nonetheless.

There were a few changes that were made in addition to the ones needed for verbosity levels. Those include the following:

• the nanorc name was replaced with the more generic dunerc name
• the new basic_checks common function for verifying successful running of the integrationtest fixtures is now being used
• the printouts that happen when tests are skipped were moved to the test_dunerc_success function to better match other test files

Please see the suggested instructions for testing these changes in DUNE-DAQ/integrationtest#152.

Type of change

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

Testing checklist

• Full set of integration tests pass (dunedaq_integtest_bundle.sh)
