[2.3.0] Checkmk Werk 16465 created: service discovery: introduce functionality to fetch job status from remote sites

[//]: # (werk v2) # service discovery: introduce functionality to fetch job status from remote sites key | value ---------- | --- compatible | yes version | 2.3.0b1 date | 2024-01-29T10:23:24+00:00 level | 1 class | fix component | rest-api edition | cre Prior to this werk, the service discovery endpoints were restricted to the local service discovery background job. This resulted in the following endpoints being restricted to local setups only: * Show the last service discovery background job on a host * Wait for service discovery completion This werk fixes this and now also supports distributed monitoring setups. To benefit from this change both the central site as well the remote sites need to be updated to the werk's version. This change does not affect local only setups.
