What problem does this PR solve?

What is changed and how does it work?

1. remove /tools, /hack/tools and /vendor. All go tools are installed by GOBIN=$OUTPUT_BIN go install.
2. github CI will use go version specified in go.mod
3. there are some conflicts that needs to be processed manually in pkg/apis, pkg/client if you are actually using go 1.18 or above. Checks are supported locally by modifying hack/boilerplate/boilerplate.py or so. But CI go version is still 1.16, posting files generated by 1.18 or above will fail.
4. add cache for github actions
