Rationale for this change

The issue with http_metric was encountered when the test was converted to sqllogictest about 2 months ago. The problem is that http_metric has dependencies, but the order of executing sqllogictest in the query_server/sqllogicaltests/src/main.rs based on std::fs::read_dir depends on the operating system. While it runs stably on the local macOS environment, the CI system running on x86 architecture occasionally encounters issues.

To address this, http_metric has added the following:

--#LP_BEGIN
m0,t0=t0 f0=false,f1=0.0 0
--#LP_BEGIN

and increased the sleep time to ensure that it can run independently and pass the tests.[1]

Are there any user-facing changes?
