Refine test job definition and assert logic (#14960)

Why I did it
Remove 'kvmtest-t0' and 'kvmtest-t1-lag' test jobs since all the test jobs are required (continueOnError: false) already, and will only enable one of classical and testbedV2 tests, no need to do an unnecessary 'or' compute test job.
Change agent pool to reduce cost and avoid congestion
