az deployment -- reply with Deployment Portal URL so that I can monitor the deployment

**Is your feature request related to a problem? Please describe.**

Sitting around watching a dancing plaintext `Running` status isn't always the most fun. It's more fun to watch the deployment and get green checkboxes and make me feel like it's working.

**Describe the solution you'd like**

When I deploy something using any of the `az deployment` subcommands it'd be nice if once the Deployment was Accepted the console replied back to me with a link to the Portal to go monitor the deployment visually.

The Portal Deployment experience is especially helpful when I'm deploying something that takes a long time or includes a lot of dependent deployments. Plus, if just a single part of my deployment fails, I can visually inspect, fix, and redeploy just that part that failed right from the Portal.

**Describe alternatives you've considered**

I name my deployments and go find them at the relevant scope instead.

**Additional context**
