Clusters containing nodes with a special agent would crash with the traceback

File "/omd/sites/core/lib/python3/cmk/base/checkers/programs.py", line 266, in _make_source_args info_func = config.special_agent_info[special_agent_id]

because the special agent was missing from the configuration of the cluster.
