Updates to the itwinai SLURM builder [WIP]

[jarlsondre]

Summary

This issue contains wanted improvements to the itwinai SLURM script builder. List of potential improvements:

• Generalized script for using the builder
  • Currently the itwinai SLURM script builder requires you to make a dedicated Python file for each use case, which can be cumbersome and also means worse maintainability. Having a single script somewhere that could be overridden would not only serve as a template but also mean that if a use case does not require a specialized script then they can simply use the built-in one.
• Integration of the SLURM config into pipeline files, if applicable.
  • Sometimes it could be easier to store all the configurations in a single file. This could also lead to an over-generalization of the parser etc., however, so this must be taken into consideration.
