Test Steps:
1. Write 100 objects.
2. Insert 2 dkeys per object. Insert 1 akey per dkey. Use OC_S1.
3. Punch all akeys and dkeys.
4. Call list_dkey() and list_akey() on the objects.
5. Verify the metrics below.
--- Metrics tested ---
1. engine_pool_ops_dkey_enum
Number of list_dkey() calls made to each object. Since we create 100
objects and call this on all of them, we expect this value to sum up to
100.
2. engine_pool_ops_akey_enum
Number of list_akey() calls made to each dkey. We create 2 dkeys per
object and there are 100 objects, so we expect this value to sum up to
200.
3. engine_pool_ops_dkey_punch
Number of dkeys punched. There are 200 dkeys total and we punch them one
at a time, so we expect this value to sum up to 200.
4. engine_pool_ops_akey_punch
Number of akeys punched. There are 200 akeys total and we punch them one
at a time, so we expect this value to sum up to 200.
5. dkey enum active and latency

engine_io_ops_dkey_enum_active_mean
engine_io_ops_dkey_enum_active_min
engine_io_ops_dkey_enum_active_stddev
engine_io_ops_dkey_enum_latency_max
engine_io_ops_dkey_enum_latency_mean
engine_io_ops_dkey_enum_latency_min
engine_io_ops_dkey_enum_latency_stddev
Active means the number of list_dkey() called at the same time. e.g.,
If 2 calls are made simultaneously and that's the highest, we would see
engine_io_ops_dkey_enum_active_max = 2. However, in this test, we expect
the max to be always 1 because making it more than 1 isn't
straightforward.
Latency is the time it took to process the list_dkey() calls. The slight
difference from active is that min would contain the actual latency and
not 0 when there's at least one call.
6. akey enum active and latency
engine_io_ops_akey_enum_active_max
engine_io_ops_akey_enum_active_mean
engine_io_ops_akey_enum_active_min
engine_io_ops_akey_enum_active_stddev
engine_io_ops_akey_enum_latency_max
engine_io_ops_akey_enum_latency_mean
engine_io_ops_akey_enum_latency_min
engine_io_ops_akey_enum_latency_stddev
Same idea as dkey. We also expect to see very similar output as in dkey.
7. dkey punch active and latency
engine_io_ops_dkey_punch_active_max
engine_io_ops_dkey_punch_active_mean
engine_io_ops_dkey_punch_active_min
engine_io_ops_dkey_punch_active_stddev
engine_io_ops_dkey_punch_latency_max
engine_io_ops_dkey_punch_latency_mean
engine_io_ops_dkey_punch_latency_min
engine_io_ops_dkey_punch_latency_stddev
Same as 5 except we're measuring the active and latency for
punch_dkeys() calls.
8. akey punch active and latency
engine_io_ops_akey_punch_active_max
engine_io_ops_akey_punch_active_mean
engine_io_ops_akey_punch_active_min
engine_io_ops_akey_punch_active_stddev
