This comprises of the service file to be copied into the systemctl directory,
plus Bridgehead start and stop scripts for both systemctl and for the
administrator on the command line.
The start-up logic for TransFAIR is specific to the ECDC/EHDS2 Bridgehead,
and did not belong in the TransFAIR repo. This commit fixes that.
It also honours the change of the TransFAIR branch name for this
project, "ehds2".
This auto-build functionality is a workaround for a bug, described in README.
The README now has additional documentation for EHDS2.
The root certificate files have been expanded to contain certificates for
both the ECDC and the DKFZ setup.
