- improved error reporting in EroPathToHops
- implemented logic to synthesize a dummy path for single-device service requests
- improved identification of interdomain pathcomp requests

- extended to support inter-domain path computation

ECOC'22 test:
- added CTTC OLS and Automation component deployment to script

Common:
- corrected DeviceType name for transponder

Compute:
- added bearer definitions for ECOC'22 demo
