Rewrite of cluster lesson

[psteinb]

• pushing the story to full bloom (just before using the scheduler)
• correcting mistakes on prefixes on Byte counts (gibi versus giga)
• refresh on ssh/scp

[Carreau]

That looks good to me. There are probably some possible refinement, but it feel like a better gradual approach.

[psteinb]

@Carreau please have a look at that single review comment I left unresolved for now. Would be cool, to merge soon.

What is the status of this PR ? , if my latest PR (Fix styling fix#35) is integrated then this one will face conflicts.

[psteinb]

This PR was reviewed by @tkphd yesterday. I am working on a fix to follow his suggestions.

[tkphd]

Thanks, @psteinb. Merge conflicts are natural, @Sabryr, and enforcing the 100-character alignment rule should not be a great challenge regardless of the merge order.

I use meld to resolve merge conflicts in my local copy of the repository. It comes in handy.

[psteinb]

As @Sabryr is waiting upstream for this PR, @tkphd @Carreau could you please have a look again and re-review or merge, please.

[aturner-epcc]

I think we merge this one and plan who is doing what with regards to automatic includes going forwards.

[tkphd]

Confirmed: this change produces lola@cray-1. LGTM.

Optional suggestion is to remove workshop_ from the variable names before merging.

[psteinb]

Thanks to @tkphd @Carreau for their reviews. I think this pushed the quality of this PR upwards quite extensively. It's wonderful to see the community helping to create some great material for HPC training.

@Sabryr @aturner-epcc Ready to go downstream.
