Nadav Har'El 03d67440ef alternator: test additional metrics and fix another broken counter
In issue #9406 we noticed that a counter for BatchGetItem operations
was missing. When we fixed it, we added a test which checked this
counter - but only this counter. It was left as a TODO to test the rest
of the Alternator metrics, and this is what this patch does.

Here we add a comprehensive test for *all* of the operations supported
by Scylla and how they increase the appropriate operation counter.

With this test we discovered a new bug: the DescribeTimeToLive operation
incremented the UpdateTimeToLiveCounter :-( So in this patch we also
include a fix for that bug, and the new test verifies that it is fixed.

In addition to the operation counters, Alternator also has additional
metric and we also added tests for some of them - but not all. The
remaining untested metrics are listed in a TODO comment.
