How to be able to run the experiment across different testbes.

Describe the solution you'd like
For the moment some values are hardcodes on the templates.

Instead put these values on the values file for that they can be configurable by helm.

Additional context
For a more generic approach, we could create a top-level value files that contain the resource specifications for AWS instances (small, large, ...).

The generic resource specs (values file) will go to a base chart that will be inherited by all other frisbee charts.
