Refreshing access tokens

[crspybits]

Neebla v1 had automatic access token refreshing. I haven't added this to v2. I need to come up with a strategy to do this.

There are four starting points for network requests:

func sendRequestTo(_ serverURL: URL, method: ServerHTTPMethod, configuration: RequestConfiguration? = nil, completion:((_ serverResponse:[String:Any]?, _ statusCode:Int?, _ error:Error?)->())?) {

func upload(fileUUID:String, uploadObjectTrackerId: Int64, from localURL: URL, toServerURL serverURL: URL, method: ServerHTTPMethod) -> Error? {

func download(file:Filenaming, downloadObjectTrackerId: Int64, fromServerURL serverURL: URL, method: ServerHTTPMethod) -> Error? {

func sendBackgroundRequestTo(_ serverURL: URL, method: ServerHTTPMethod, uuid: UUID, trackerId: Int64, requestInfo: Data? = nil) -> Error? {

What if: I have a timer set that, while the app is in the foreground, periodically, the access token gets refreshed? This way I don't have to muck about with the network request code.
