Add timeout to SO to wait for success

The timeout implementation assumes that a finished request is a HTTP-200
together with either a request state of COMPLETE or FAILED in the embedded
request in the response in the JSON. This is the same as what is done earlier
in this class and in, for example, VFC.

Unit test for timeout has also been added.
