Refactor local registry and dynamically fetching stack images

[pacostas]

Summary

This PR:

• transfers the functionality of spawning a new local registry with crane from jammy-tiny-stack in to tools.sh. The registry functionality has been transferred to a common place (tools.sh) as it will also be used in the future on the receipts in combination with multiacrch as is implemented at the moment on jammy-tiny-stack
• dynamically iterate over the stacks on the integration tests by fetching them from the images.json. Removing that way the hard coded versions of stacks.
• Same code works with jammy-base-stack.
