az sql copy db to support copy from elastic pool into a single db

**Is your feature request related to a problem? Please describe.**
I want to be able to copy a database with elastic pool (from production) to a server where elastic pool doesn't exist (development).

**Describe the solution you'd like**
Ideally I want to provide an sku tier via parameter, so that the destination sku doesn't depend on the source. It works with Azure Powershell as well as the azure portal.

**Describe alternatives you've considered**
Create an elastic pool first, then copy the db there, then move it out of the pool, then delete the pool. A bit cumbersome, isn't it?

**Additional context**
The functionality above is required to script the automatic setup of a feature-branch environment. I want a fresh copy of the prod database on the dev server. The rest of the environment configuration is done via k8s helm chart.
