[DAEMON-77] appcd: Extend CI process to create platform-specific bundles

The current Jenkinsfile introduced by DAEMON-43 runs check and coverage tasks, then bundles the daemon distribution without NPM dependencies. DAEMON-56 introduces a gulp package-bundle that will run npm install and re-package the daemon distribution tgz file. This ticket is to add the gulp package-bundle to the CI process where it is executed on the following 5 Jenkins slave machines: * macOS * 64-bit Windows * 32-bit Windows * 64-bit Linux * 32-bit Linux The resulting tgz file is to be uploaded as an artifact of the CI job.
