Port configuration to preCICE adapter schema

[uekerman]

The precice-settings.json should be ported to the preCICE adapter schema.

Currently (using the regression test)

{
    "coupling_params": {
        "participant_name": "SolverOne",
        "config_file_name": "../precice-config.xml",
        "mesh_name": "MeshOne",
        "write_data_name": "dataOne",
        "read_data_name": "dataTwo"
    }
}

Adapter schema: https://github.com/precice/preeco-orga/blob/main/adapter-config-schema/precice_adapter_config_schema.json

Easiest way to experiment: https://www.metaconfigurator.org

Example:

{
  "participant_name": "SolverOne",
  "precice_config_file_path": "../precice-config.xml",
  "interfaces": [
    {
      "mesh_name": "MeshOne",
      "write_data": [
        {
          "name": "dataOne"
          "solver_name": "write_data"
        }
      ],
      "read_data": [
        {
          "name": "Heat-Flux"
          "solver_name": "read_data"
        }
      ]
    }
  ]
}

solver_name should be used to model the FMU names, which are currently specified in fmi-settings.json

Note: The example also currently violates the naming conventions.
