Currently, master branch is vulnerable that can be Squash and merge without CI green.

The job in .travis.yml "./scripts/ci/reject_master_prs.sh" has not taken effect.

This would be dangerous.

This could be configured in repo settting. what's the impact of mark CI as required for PR today? If impact is clear, I can do it.

@jiasli suggest that master branch is useless for now, no need to enable this.

@yungezz @yonzhan @jiasli @zikalino Could one of our azure-cli repo admin disable Travis for this?
