CI/CD

Enable CI/CD with GitHub Action. The following workflows have been applied to numbersprotocol/capture-lite and work perfectly.

• Automatically run npm run test on push or pull request.
• Automatically run npm run lint on push or pull request.
• Automatically upload code coverage reports to Codacy.
• Automatically release on the develop branch when the version property in package.json changed.
  • Create a pre-release with version and tag name.
  • Upload APK file to the release page.
• Automatically update a demo web page (ionic build) on gh-pages branch.

We should mock LedgerService for the unit tests (e.g. record-repository.service), and thus the automatic workflows will not be affected by the IOTA status.
