Separate the snap by cuda version on v4

[gabrielcocenza]

From the transition from v3 to v4, dcgm now separate the debian packages based in the cuda version.

This approach tries to have a single branch to pack and distribute several dcgm snaps based in the cuda version.

snapcraft.yaml.in acts like a template and the right values can be added by running:

 CUDA_VERSION=13 envsubst '$CUDA_VERSION'  < snap/snapcraft.yaml.in > snap/snapcraft.yaml

With this kind of approach it's possible to dinamically generate the snap and dependencies to be build

#69

LGTM, but remember to update the documentation in snapcraft.yaml.in once the snap track management and release strategy are defined. I suspect you will need to do more than sudo snap install dcgm e.g. sudo snap install dcgm --channel v4-cuda11

Looks good to me.

Follow-ups I'd like to see:

• Document the snap track policy.
• Provide a reproducible local snap build—via a Makefile, a tox target, or clear documented steps.

@gabrielcocenza I think we will need a special release and promote actions for each track, is it something in the scope of this PR?

[gabrielcocenza]

@Deezzir I'm waiting for snapcraft team approve the creation of the new tracks.

After they approve, we can touch the release and promotion part

Overall LGTM, left some comments to address, I am concerned about the formatting the most, if you have admin access to the DCGM listing, you can copy/paste to check the final result

LGTM, thanks for addressing the comments

Thanks for working on this.
