performance-metrics: Add standalone qcow2 perf tests

Browse source 
Add performance tests for standalone qcow2 images without backing
files - uncompressed, zlib and zstd compressed. Each variant
includes single queue and multiqueue tests for sequential
read, random read and warmed up sequential read.
