    [#8937] fix(core): Fix flaky test in testPolicyAndTagCacheWeigher (#8931)
    
    ### What changes were proposed in this pull request?
    
    Comment out the flaky test cases.
    
    ### Why are the changes needed?
    
    As the weight mechanism in the Caffeine cache is probabilistic, the CI
    pipeline will fail occasionally(failure rate is about 10% or so).
    
    Fix: #8937
    
    ### Does this PR introduce _any_ user-facing change?
    
    N/A.
    
    ### How was this patch tested?
    
    The existing tests.
