How is a managed object made aware of the existence of a new property so that the object can affect, or be affected by the property?
Properties in AppCenter are not directly seen inside an object or server. Property values could be passed to a server via the command line. Particular properties can be accessed from AppCenter by using the supplied API. Also the values could be used to define environment variables and the server could access those. User properties are normally used to define things like environment variables, define start directories, command line options, and things like that. There is currently no direct interface to send properties to an object.
