Allow modifying exsiting artifact

[xavier-romero]

Background & motivation

For testing upgrading versions of production environment I'd like to use Kurtosis to fully reproduce/document the procedure.
For this, I'd love to have the option to modify artifacts, specially for stopped services (as I can open a shell and do manually for running services).
As sometime I need to stop a service, modify another things, and then the service NEEDS a modified artifact to start again. That can not be achieved right now.

Desired behaviour

I'd like to be able to do something like this:
kurtosis files download cdk whatever_file
edit file locally
kurtosis files upload cdk whatever_file --restart-services-using-it
Whatever impact it could have on rest of the stack is under user responsability.

How important is this to you?

Painful; the lack of this feature makes using Kurtosis frictionful.

What area of the product does this pertain to?

CLI: the Command Line Interface
