[Core feature] Remove Storage config requirement for fast registration

[EngHabu]

Motivation: Why do you think this is important?

Fast registration is one of the more convenient ways to iterate over code. Requiring local access to remote storage (s3, gs... etc.) is quite a barrier to use though.

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

flytectl register shouldn't require storage config
pyflyte/flyteremote register shouldn't require storage config

Describe alternatives you've considered

Exposing a service to mint signed urls but the UX is still ugly (requires copy pasting... etc.)
