"Kubernetes Development Automation" is outdated

[xiangpengzhao]

Kubernetes Development Automation has some outdated contents, e.g. in "Ready to merge status", we now

• use cncf-cla instead of cla
• label lgtm by /lgtm instead of LGTM
• allow PR to be ready to merge when it has both lgtm and approved

We should go through the doc to find all that needs to be updated. We will also have to update all the associated docs when we change the contribution process in future, including PR/issue reporting/automation but not limited.

Pull Request Process also need to update.

e.g.:

If the failure is a flake, a member can comment @k8s-bot [e2e|unit] test this issue: #

Not much bandwidth for this right now, but if/when I can contribute I will. Happy to review if someone else takes a crack at this.
