**CLI** user should NOT see a **diff** when **removing services**

Context

Removing service instances from a manifest does not unbind them from the app or delete the service instance. Showing service instances removed from the manifest in the diff can confuse people into thinking the service instances will be unbound and/or deleted.

Acceptance Criteria

Omit Instance Removals

Given an app named my-app
And it is mapped to two service instances one and two
When I apply the following manifest

---
applications:
  - name: my-app
    services:
    - two

Then the service instance one should not show up as being removed in the diff

Note:

• Pro tip for creating service instances: Try using the cf cups command (create-user-provided-service).
• The manifest diff endpoint should not return service instance deletions, so this logic can be shared across all clients

Start at the manifest diff endpoint and reproduce the case with an app mapped to service instances one and two, then apply a manifest containing only two. Done means the diff omits service instance one while the issue's behavior remains limited to diff reporting, without unbinding or deleting the service instance.
