The REST API endpoints "Show all monitored services" and "Show the monitored services of a host" were previously accessible via the GET method. This caused a limitation of the maximum size of query parameters.

A common practice is bypass this limitation is to use a POST request. Other werks like 17003 have already implemented this change for some other endpoints.

This werk changes the two aforementioned endpoints to POST. The GET versions will continue to work until Checkmk version 2.5.
