prevent CI from fast fail when just one k8s version e2e failed

[chaosi-zju]

What type of PR is this?

/kind flake

What this PR does / why we need it:

We now run e2e test on multi releases version of Kubernetes, if e2e test failed at just one releases version, the other e2e test will be interrupted by fast fail strategy.

It is not conducive to check the root cause of failure, so it is advised to disable fast fail strategy.

I don't quite understand why disabling fail-fast can make it easier to quickly locate problems. Can you explain the reason a little bit?
