Make ImageBuildSpec work with enclave edits

[tedim52]

Background & motivation

Right now if you use an ImageBuildSpec like so:

def run(plan, args):
     plan.add_service(name="service", config=ServiceConfig(
           image=ImageBuildSpec(
                  build_context_dir="./Dockerfile",
          )
      )
    )

Desired behaviour

If you run an enclave, the docker image is built and the service starts off of it.

Ideally, if I make a change to the underlying code the docker image containerizes, I can leverage enclave edits to only restart the service with the rebuilt image.

However, right now this isn't detected by our interpreter so rerunning the package will not detect an update on add_service and not rerun the service, as desired.

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?
