[chectl] [ux] Reorder/relabel successful deployment messages

[nickboldt]

Is your enhancement related to a problem? Please describe.

Current deployment success message is great, but could be reordered a little for better grouping of content.

As of che-incubator/chectl#913 we have:

  ✔ Show important messages
    ✔ [ACTION REQUIRED] Please add Che self-signed CA certificate into your browser: /home/tolusha/cheCA.crt.
   Documentation how to add a CA certificate into a browser: https://www.eclipse.org/che/docs/che-7/overview/importing-certificates-to-browsers/
    ✔ Eclipse Che 7.20.0-SNAPSHOT has successfully installed.
    ✔ Users can access the Dashboard at   : https://che-che.192.168.99.100.nip.io
    ✔ Plugins can be viewed at            : https://plugin-registry-che.192.168.99.100.nip.io/v3
    ✔ Devfiles can be viewed at           : https://devfile-registry-che.192.168.99.100.nip.io
    ✔ Identity provider can be accessed at: https://keycloak-che.192.168.99.100.nip.io/auth
    ✔ Product documentation is at         : https://www.eclipse.org/che/docs/
    ✔ Eclipse Che admin credentials       : "admin:admin". You will be asked to change default Che admin password on the first login.
    ✔ Identity Provider credentials       : "admin:qzwHgv9ZkHdP"

I'd suggest we reorder/relabel that a bit. See below.
