REL-2307: P1-monitor does not handle classical proposals

This is a hotfix to let P1-monitor process classical and queue proposals, as it is needed for the new korea backend.

A hotfix would require a version change, however there is no p1-monitor-master version. Instead we rely on the pit version but that may be wrong. Do you think we should have a separate version and change the build?

As a hotfix I need to merge to both develop and p1-monitor-master. The latter cannot be done on GH and will be done manually after the merge to develop
