Invoked when the OTP authentication process completes.
void onComplete(boolean success)
Invoked when the OTP authentication process completes. If authentication is successful then it is assumed that the proper HTTP cookies have been received and set.
To this end, a strategy implementation must make sure that all the cookies that represent a successful authentication are present in the active CookieManager.
If the strategy implements a mechanism that utilizes a different cookie storage then these cookies must be copied over to the current default cookie manager (accessible via
CookieHandler.getDefault()) before invoking this method with a true argument.
success - true if the redirect back to the finish endpoint containing the finish endpoint URL parameter was detected, false if the flow failed for a reason
