socketDocumentId on connection errors

[vladsud]

We have a bunch of reports where we fail to connect to ordering service in SPO driver and we have no correlation ID to connect with server logs.
We have successful joinSesison call, and thus ISocketStorageDiscovery.id that we report (on successful path) as socketDocumentId in the rest of our telemetry.
But here, connection fails, so we never report any correlation ID (this one, or clientID), and thus we have nothing to work with.

Can OdspDocumentService.connectToDeltaStream() add socketDocumentId property to error object before it re-throws it?

I believe that's enough to get all the data we need.

If possible, we should fast-track it into 0.27 to faster understand the problem.

@ksbrar , @skylerjokiel - FYI, I think that's trivial change that can speed up investigation of connection issues reported by Dan & Kyle.
