Unsubscribe from a rate plan does not work with developerId, only email

[minnur]

Q	A
Bug?	yes
New Feature?	no
Version	2.0.0

Actual Behavior

When trying to unsubscribe from an existing rate plan I get this:
URL id qualifier [email@email.com] does not match with the entity id [someID-0839-4057-84fc-...] or some of these entities may not exist

Expected Behavior

Successfully unsubscribe form a rate plan.

Steps to Reproduce the behavior

The code for the subscribe/unsubscribe is in my fork. I am trying to create a patch that would temporarily solve this issue or give some ideas on how this issue could be better handled in the library.

Proposed Solution

Looks like Apigee\Edge\Api\Monetization\Normalizer\EntityNormalizer::normalize needs a special treatment for the developer ID when calling unsubscribe method. While developer entity ID is used for the subscribe to rate plan is used the unsubscribe requires actual email address as a Developer ID.

We should not be using anything but email addresses as an ID for developers. The older client library only used developerId in one location and it broke after internal changes (CPS migration). We needed to change that code to use email instead of developerId. The developerId is not guaranteed to be unique.

Here is payload example when trying to unsubscribe:

{"created":"2018-11-29 00:06:36","developer":{"id":"someID-000-0000-84fc-..."},"endDate":"2018-11-28 09:07:33","id":"...-0000-subscriptionID-0000-...","ratePlan":{"id":"10_cents_rate_planID"},"startDate":"2018-11-28 15:15:00","updated":"2018-11-29 00:06:36"}

That developer[id] ='someID-000-0000-84fc-...' should be email address.

Here is my ugly patch so you get the idea what I am trying to achieve.
