Whitelist test and enforce test order

[TheRealHaoLiu]

SUMMARY

occasionally we get CI failure when running the test with

awx_test.yml testcase fail with

"job_explanation": "Job reaped due to instance shutdown",

I suspect that this is due to the fact that awx_replicas_test.yml is run before awx_test.yml (and we end up with 3 replicas) and during awx_test.yml we scale down the replica back to 1, if we try to run job too early we end up with job being potentially schedule to one of the replica that will get scaled down

causing flaky CI
