How to publish xprofiler

v1.x

• git fetch origin master
• git checkout v1.x-staging
• git reset --hard origin/master
• edit package.json, set release version
• git push -f v1.x-staging
• git tag ${release version}
• git push origin ${release version}
• npm pub

Attention: if ci is broken, we need to move the npm latest tag to the previous release version.
