Bugfix: Convert int/float parameters (2nd try) (#1851)
* If a step declares a parameter of type string, depending on how the config is written, it is no longer ignored, if it is interpreted by the yaml parser as integer or float value.
* If an expected parameter is present in the configuration, step execution will consistently fail if the parameter has the wrong type, no sensible conversion can take place, and it is known that the parameter will be ignored.
* For all type-mismatches that have no implemented conversion, a warning is logged. (It isn't known whether the conversion actually works, since it depends on both the yaml and json packages and future changes there.)
* Entries in the evaluated config with a value of nil are ignored.
