"Scale from 0" and "MultipleFuncInvoke" tests often fail in vHive CRI CI

[ustiugov]

Describe the bug vHive CRI tests exhibit a sporadic (but quite frequent) failure when scaling microVMs from 0:

1. === RUN   TestAutoscaler/Scale_from_0
   === CONT  TestAutoscaler
   cri_test.go:166: 
           Error Trace:    /root/_work/vHive/vHive/cri/cri_test.go:166

                                       /root/_work/vHive/vHive/cri/cri_test.go:109
           Error:          Received unexpected error:
                           rpc error: code = DeadlineExceeded desc = context deadline exceeded
           Test:           TestAutoscaler

   --- PASS: TestAutoscaler/Scale_fn_with_concurrency_1 (8.58s)
   --- FAIL: TestAutoscaler/Scale_from_0 (260.04s)

2. === RUN   TestMultipleFuncInvoke
   cri_test.go:167: 
           Error Trace:    /root/_work/vHive/vHive/cri/cri_test.go:167
                                       /root/_work/vHive/vHive/cri/cri_test.go:132
                                       /root/_work/vHive/vHive/cri/asm_amd64.s:1571
           Error:          Received unexpected error:
                           rpc error: code = DeadlineExceeded desc = context deadline exceeded

   --- FAIL: TestMultipleFuncInvoke (60.04s)

Hence, we exclude these tests from the CI until a fix is found.

No, it is not fixed, there will still be sporadic failures
