Add a download feature to the CLI's retrieve feature

[bhermann]

Is your feature request related to a problem? Please describe.
When inspecting an artifact's available information users might want to retrieve the artifact itself too.,

Describe the solution you'd like
When executing a retrieve command for a specific artifact a user should be able to specify whether they would like to have the original artifact retrieved too. The download should be organized in a folder where it would not conflict with other download happening at another time or for a different artifact.
The download should be accompanied with a data file describing the retrieve query used, the results of this query, the versions of both client and server, url of the server used, and date/time of execution.

Describe alternatives you've considered
none

Additional context
none
