[Core feature] Add --copy none to pyflyte run --remote

[thomasjpfan]

Motivation: Why do you think this is important?

If you are using pyflyte run --remote with ImageSpec and source_root, then the copy mode is LOADED_MODULES. This means that during image build time the files are injected into the image itself. This means that we do not need to use fast-registration anymore.

Goal: What should the final outcome look like, ideally?

Allow for pyflyte run --remote --copy none

Describe alternatives you've considered

Do not introduce the feature. This means that the same files will be in the image and also be downloaded during pyflyte-fast-execute.
