Integrate SkyWalking-eyes to check license headers in CI

Enhancement

Integrate SkyWalking-eyes to check license headers in CI.

For some new contributors, they may do not know the license header is required, we can use the GitHub Action and check license headers in CI automatically.

Hi @fgksgf , Thanks for creating this issue!

I think it is a good point we enable license checker in CI. In my opinion, you can directly create a PR and let's see how this action works on our repo. Then if it is good to go, we push it to merge.

No problem, I will do this :)

I locally checked the project with SkyWalking-eyes, and found that almost all license headers have one less sentence compared to the standard one.

Well, the missing line is "WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.", I think this sentence is critical and a modified Apache license header is not called Apache license actually. It's better to add it back.

I'm working on fixing them.

@tisonkun We may need create an issue to track the ignored files in .github/.licenserc.yaml.

Yes. Would you like to create one for them?
