"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:

=== 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:99
        	            				/root/_work/vHive/vHive/cri/cri_test.go:109
        	Error:      	Received unexpected error:

        	Test:       	TestAutoscaler
        	Messages:   	Failed to get response from function

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

=== 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
        	Test:       	TestMultipleFuncInvoke

--- 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
