attach specific drivers to use for gpu

[Nishant Dash]

It would be nice if we could specify drivers we wanted to use for gpus through the charm.

For example, we could download our own drivers and binaries if needed and `attach-resource` those drivers and let the charm know to use that as an alternative to apt installing the latest packages of a source or disabling gpus and manually installing the binaries.

A similar use case exists for Nova for which it has a charm to help with gpu binaries: https://charmhub.io/nova-compute-nvidia-vgpu

We need to be able to define the version of GPU drivers. Also, the drivers should be signed properly so that Secure Boot works by default.

The charm currently lets the use configure nvidia apt key urls, apt sources, and apt packages for the nvidia drivers [1]. Are there situations where this doesn't specify enough level of detail to install the correct drivers?

Doesn't that only let you add package names? in which case you end up with the latest of your respective package instead of a specific version
