action invocation result

[fatadel]

node-wot approach:

Direct result of an action is returned when invoking an action.

---

wot-py approach:

Invocation id is returned when invoking an action. Direct result of an action should be fetched from a separate endpoint.

The behavior described in the "wot-py approach" is true when using a custom client.
When using the wot-py servient as a client the behavior is the same as the "node-wot approach", apparently because the servient handles all the additional work.
