Implement remote assets

[hulto]

Is your feature request related to a problem? Please describe.
Right now we don't have an easy way to take a tome from local testing with golem into production.
Currently every instance of assests.* has to be replace with a file.download and file.* function.
To avoid this we should implement a remote option to the assets module.

Describe the solution you'd like

1. Create a new dictionary tavern_remote_assest using the pattern set by input_params that's passed into every tome.

   • This dictionary will track file names ---> remote asset links.
   • If a file name isn't found as a key of tavern_remote_assest then it's not a remote asset.

2. Implement remote versions of each assets function:

   • Use the current callback URI
   • Transparently acces the tavern_remote_assest dict with something like the following:

use starlark::eval::Evaluator;

pub fn list(starlark_eval: &mut Evaluator) -> Result<Vec<i32>> {
    let tmp = starlark_eval
        .module()
        .get("tavern_remote_assest")
        .context("Failed to get 'tavern_remote_assest' ")?;
    unimplemented!();
}

- Translate the asset name `persist_service/systemd_service.j2` to a downloadable URL `https://<CALLBACK_URI>/cdn/download/Bundle-504b83fae75bc5c068803d59311ce53babf71bde2c49142a4d20cda91c8e6f08` using the `tavern_remote_assest` dictionary.
- download, read, or stream the content from remote asset to fulfill the assets function goal.

3. Implement a search order for assets:

   • The assets library should first check for remote files and then local ones.
     • The thought is that by allowing remote to override local we avoid situations where a local copy of something breaks the tome
   • If an asset is not found in the tavern_remote_assest dictionary then search the local Assets struct for a file with the same name.

4. Add the tavern_remote_assest Dict to the tavern ---> imix communication such that the task has the tomes unique key value pairs.
