[GitHub] Add ssh signing to your git commits

It would be nice, if we sign our commits. The process involves below steps.

• Creating ssh-keys
• Uploading ssh-keys as signing keys to GitHub
• Setting global parameters for git to sign every commit

And, then the pushed commits, will have a verified sign next to commits.
