Alamofire should more gracefully handle system interference

[jshier]

At the moment, Alamofire doesn't deal well when system frameworks or the Obj-C runtime interfere with URLSession or URLSessionTask identity.

These include:

• Use of URLProtocol, as seen in Wormholy, assertionFailure - needNewBodyStream did not find UploadRequest  #3373
• URLSession swizzling, as seen in Splunk MINT and Crittercism, Creating NXProxy for URLSession which is creating issue in RequestMap monitor class #3238.
• Others.

These sort of issues may explain reports of crashes within RequestTaskMap where the task identity is changed under the hood.

Hi, is this problem solved or it is actual bug?

It's an ongoing issue. Not really a bug, more of something Alamofire could detect and either workaround or warn about so users aren't surprised.
