/**
 * Creates a new service instance of `clazz`.
 *
 * The options passed into the constructor of `clazz` are taking from the `options` parameter.
 *
 * This function allows the user to define mock- or test objects as service references.
 *
 * Most type-checking features are disabled for convenience, but by default this function's types
 * enforce that a value provided for a reference must match the partial interface of the actually required type.
 *
 * For example, if a service depends on `{ ctx: ApplicationContext }`, this function ensures
 * that the test value for `ctx` implements `Partial<ApplicationContext>`.
 * This can of course be disabled by casting the value explicitly.
 *
 * @param clazz a service class
 * @param options options passed to the service constructor
 * @returns a new instance of the given service class
