[feature request] fuzz testing support

[huiwq1990]

What would you like to be added:

1. Add openyurt to CNCF-Fuzzing

2. Continuous fuzzing by way of OSS-Fuzz

Why is this needed:

1. Fuzz will improve openyurt security

2. Fuzz is gaining more and more cncf projects

3. Recently I write a test case for yurtappdaemon, and find a nil pointer bug

@huiwq1990 It's a good idea to add fuzz testing support for OpenYurt. and i think we can support it in the 2022 OSPP topic. @Congrool @lorrielau Do you have any comments?

Sry for late reply. I'm not familiar with the fuzzing test, a little time needed to figure it out.
