[artikell]

Enhance the test framework：

• support --loglevel：The note level now only outputs test results
• support --only： Use the ./src/valkey-unit-tests --only 'zip' command to execute only the use case of the keyword zip
• support --count：You can choose to execute multiple times
• support Time statistics：The result defaults to including execution time, like:

[ok] - test_ziplist.c:test_BenchmarkziplistCompareWithString    1       27282201.0000 ns/op
[ok] - test_ziplist.c:test_BenchmarkziplistCompareWithNumber    1       37461000.0000 ns/op
[ok] - test_ziplist.c:test_ziplistStress__ziplistCascadeUpdate  1       34700.0000 ns/op
