Use relative config paths for INFO printing

Release notes

Details

When the TQPathManager resolves a config path, it returns the absolute path. However, if the absolute path is then used during INFO printout during runtime, it is often too long and the framework cuts the path short.

Therefore, this MR sets a standard of using the relative path (originally provided in the master config) for INFO printout, while using the absolute path in other cases (such as ERROR printout).
