Complete quota tests

- Test that we properly account for deletions between count items
  runs.
- Test that we can expire objects when a bucket has a quota
  enabled.

+    Scenario Outline: Quotas are affected by deletion operations between count items runs
+        Given an action "DeleteObject"
+        And a permission to perform the "PutObject" action
+        And a STORAGE_MANAGER type
+        And a bucket quota set to 10000 B
+        And an account quota set to 10000 B
+        And an upload size of 1000 B for the object "obj-1"
+        And a bucket quota set to <bucketQuota> B
+        And an account quota set to <accountQuota> B
+        And a <userType> type
+        And an environment setup for the API
+        And an "existing" IAM Policy that "applies" with "ALLOW" effect for the current API
+        When I wait 3 seconds
+        And I PUT an object with size <uploadSize>
+        Then the API should "fail" with "QuotaExceeded"
+        When the "count-items" cronjobs completes without error
+        When I wait 3 seconds
+        # At this point if negative inflights are not supported, write should
+        # not be possible, as the previous inflights are now part of the current
+        # metrics.
+        And i delete object "obj-1"
+        And I wait 3 seconds
+        And I PUT an object with size <uploadSize>
+        Then the API should "succeed" with ""
+
+        Examples:
+            | uploadSize | bucketQuota | accountQuota | userType |
+            | 100        | 200         | 0            | ACCOUNT  |
+            | 100        | 0           | 200          | ACCOUNT  |
+            | 100        | 200         | 200          | ACCOUNT  |
+            | 100        | 200         | 0            | IAM_USER |
+            | 100        | 0           | 200          | IAM_USER |
+            | 100        | 200         | 200          | IAM_USER |
