Create branch starting with issue number

When we start working on an issue, we create a branch for that issue.

The branch name must start with the issue number.

For example, if the github issue number is 184 and if the issue is about “building sales report” then the branch name could be 184-build-sales-report.

The important thing is that the branch name must start with issue number. After the issue number the text is only to gently refer what this issue is about.
