Cannot change URLRequest's timeoutInterval

[MikeSpelling]

Description:

Using OAuth2Swift startAuthorizedRequest there is no way to override the requestTimeout. Although we can override the sessions timeout via:

let configuration = oauthswift.client.sessionFactory.configuration
configuration.timeoutIntervalForRequest = 300
oauth.client.sessionFactory.configuration = configuration

This will be overridden by the actual URLRequest's timeoutInterval used as, from Apple, https://developer.apple.com/documentation/foundation/urlsessionconfiguration:

In some cases, the policies defined in this configuration may be overridden by policies specified by an NSURLRequest object provided for a task. Any policy specified on the request object is respected unless the session’s policy is more restrictive.

In this case the OAuthSwiftHTTPRequest instantiates it's Config object which has a default timeoutInterval set to 60.
Changing the URLSession's configuration's timeoutIntervalForRequest does not seem to be able to override this.

Any update on this? I couldn't find a solution so I've created a PR at /pull/672 which solves it for me...
