Márton Elek 84ea80c1fd satellite/repair/checker: respect autoExcludeSubnet anntation in checker rangedloop
This patch is a oneliner: rangedloop checker should check the subnets only if it's not turned off with placement annotation.
(see in satellite/repair/checker/observer.go).

But I didn't find any unit test to cover that part, so I had to write one, and I prefered to write it as a unit test not an integration test, which requires a mock repair queue (observer_unit_test.go mock.go).

Because it's small change, I also included a small change: creating a elper method to check if AutoExcludeSubnet annotation is defined
