user-defined service properties

[elfenpiff]

Brief feature description

Services may have properties that correspond to sensors or other constraints that cannot be represented in the context of iceoryx2. Therefore, the user needs the ability to set user-defined properties.

Detailed information

let service = zero_copy::Service::new(&service_name)
  // START: user-defined service properties
    .custom_property("CameraResolution", "1920x1080")
    .custom_property("Framerate", "60")
  // END: user-defined service properties
    .publish_subscribe::<TransmissionData>()
    .open_or_create()?;

The user-defined service properties can be read via the services static config:

let camera_resolution = service.static_config()
                               .custom_property("CameraResolution");

Is the restriction to byte string literals necessary? Why not accept any valid UTF8 string?

@elBoberido just to test if you pay attention.
