Proposed changes

Fix a flaky system test caused by duplicate operations being executed by the mapper.

The reason why the existing de-duplication didn't work is that the operation had been completed locally before the operation notification was received for a second time from Cumulocity. Since the command was no longer "active", the mapper totally ignored the fact the operation has already been executed.

This PR adds a new recently_completed_commands store to the mapper, which stores the completed command IDs for ~1 hour to cope with this race condition where the Cumulocity operation status takes some time to update.
