Provide information for the user about technical exceptions

Migrated from NovaTec Jira. Original ticket: INSPECTIT-632

It is important that we have a proper exception handling in the CMR (at the service interface) in place and that this information is displayed to the user in a meaningful way (raw exceptions aren't very meaningful). We should add an exception interceptor for this which enhances/modifies the existing exceptions so that the UI can display some information alongside this exception etc.
