Convert bash scripts(.sh files) to javascript files

[shreys7]

Currently, the following files present inside npm folder are bash scripts

• ci-requirements.sh
• package.sh
• test.sh
• zip.sh

Change these bash scripts to javascript files, so that it becomes platform agnostic, i.e. works well on Windows, Linux or macOS. This can be achieved using the node's shelljs module.
See deepinstall.js file present in npm folder for reference.
