[feature request] Add fuzz-testing

[harshitasao]

What would you like to be added:
Fuzz testing or Fuzzing is a Black Box software testing technique, which basically consists in finding implementation bugs using malformed/semi-malformed data injection in an automated fashion.

Integrate the project with OSS-Fuzz by following the instructions here.

Why is this needed:
To increase the security posture of the project.

Part of #1706

Maintainers help is highly appreciated. For example, helping in identifying the components where fuzz testing will be added.

openkruise is driven by CRD manifests，and crd will be validated by webhook. I am not sure how semi-malformed data can be used to test openkruise, are their any example in related project, e.g. kubernetes project ?

@furykerry There are CNCF fuzzzing projects in https://github.com/cncf/cncf-fuzzing and kubernetes also has its fuzzing tests https://github.com/kubernetes/kubernetes/blob/master/pkg/api/testing/fuzzer.go.

I would like to try to use OSS-Fuzz to establish a continuous fuzzing set up for kruise.
