No way to check from SCP callbacks identity of peer

Currently there is no way to know from within the SCP callbacks which peer is calling us, or even which association invoked this callback. For the latter problem, I added in #97 the sop_class.ServiceClass instance, which contains a reference to the association. However, neither the ServiceClass handler, nor the Association, keep a record of (for instance) the Calling AET. One way to mend this, would be to keep the Calling AET inside the Association object, and then pass the ServiceClass object to all callbacks (I can draft a PR). Other suggestions?

I added this functionality to the association, but apparently never set it up as a PR. You can see the implementation here: https://github.com/amosonn/pynetdicom3/commit/62b3b6d71eaab3a80f99bb1cade124f6df463ee6, I’ll try to wrap it up and submit it later. It belongs to my branch https://github.com/amosonn/pynetdicom3/tree/all_together , but I wouldn’t recommend working with it, I change it very often.

The calling AE title is now accessible via the info parameter that gets passed to the callback: info['requestor']['ae_title']. The requestor’s port and IP address are also available.
