Anatol Belski c3312dca3f performance-metrics: Add qcow2 punch hole micro benchmark ...

Add micro_bench_qcow_punch_hole which times punch_hole calls through
QcowSync on a prepopulated qcow2 image. Each call deallocates one
cluster exercising deallocate_bytes with refcount decrement and
fallocate punch_hole on the host file.

Two TEST_LIST entries: micro_block_qcow_punch_hole_64_us and
micro_block_qcow_punch_hole_256_us with 64 and 256 cluster workloads.
