Use JSON schema for configuring IC properties
Externally managed ICs can be configured by setting certain parameters. E.g. IP address of OPAL-RT Target or Docker image of Kubernetes simulator.
These properties are specific to each IC type (similar as the start parameters are specific to each IC type).
We should support a JSON schema definition of these IC properties in the same way we intend to do this for the start parameters in #294 (closed). (Providing customized form elements)
