Add support for sandbox multi-image per repo #738
Description
For projects that have a Node.js front-end component and a Python back-end component that share the same repository, DAIV needs to be configured with an image that has both technologies installed. Otherwise, it will struggle to run commands on one of the components.
To mitigate this, the repository could allow the user to configure two images that the LLM would need to choose from before running commands. The LLM could then pass that choice as a parameter to the bash tool. The images would need identifying names to make it clear to the LLM which to choose.
