Title "Check_MK Agent" service: Combine with new plugin service

Compatibility Incompatible - Manual interaction might be required

This werk reorganizes the way information about the agent deployment is presented.

It is only incompatible for users that configured rules using the rule "Checkmk agent plugins", which was only present in Checkmk version 2.1.0b1. That rule is deprecated and must be reconfigured accordingly. You can configure expected versions using the ruleset "Checkmk Agent installation auditing". No further action must be taken.

The general idea now is that the Check_MK service will monitor the operational aspects of the installation. It will report connection errors, missing data, parsing errors and the execution time.

The service "Check_MK Agent" now includes everything regarding the deployment of the agent, i.e. the agents version, last updates, agent plugins, IP allow lists and the like.

Since the service no longer exclusively deals with information regarding the agent update, the service check command is changed from check_mk-check_mk_agent_update to check_mk-checkmk_agent.
