Adds a ListServiceStatuses method. This does server-side computation of service desired vs running tasks. This is a very common operation on the client, but performing it previously required getting a list of all tasks for a service, which was both network and computationally expensive.

The TestUpdaterRollback tests are known flaky, and I am going to merge if I get a test run that is green, unless I see an error unrelated to TestUpdaterRollback. |

- What I did
Added a gRPC method
ListServiceStatusesto the control API. This performs the extremely common UI operation of calculating service actual vs desired tasks on the server side, which reduces the amount of work and number of network requests required by clients.- How I did it
Counting up tasks, EZPZ. Global services are checked with the standard trick of looking at all tasks in desired state running.
Using a new gRPC method avoids having to change the
Serviceproto to accommodate what is essentially fleeting UI data.- How to test it
Includes a robust unit test
- Description for the changelog
swarmkit now supports querying service task actual and desired counts directly, allowing for optimizations in the engine as well.
