Hello-seqera

[kenibrewer]

This adds the first two sections of hello_seqera a training module intended to provide a hands-on approach to learning Nextflow.

The main portions covered are:

1. Running Nextflow jobs from the cli -with-tower.
2. Launching nextflow runs within Seqera Platform in a pre-configured compute environment.

I had intended to include more content including a simulated Compute Environment setup, but I decided that approach needs more work (specifically we need to figure which of the HPC executors we can run from within a Devcontainer). That partial work has been moved into #420.

A few early comments, apologies if you weren't looking for review just yet, @vdauwera pointed me in this direction ;-)

Thanks @pinin4fjords for the early comments. Unfortunately, many of the comments related to things that I had just copied over from your guide and planned to rework.

The part of the PR that is now ready to review is Part 1 indocs/hello_nextflow/seqera/01_run_with_cli.md.

I sketched out the outline of what I plan to do for Parts 2-4 in the following files:

• "docs/hello_nextflow/seqera/02_run_with_launchpad.md"

• "docs/hello_nextflow/seqera/03_add_compute_environment.md"

• "docs/hello_nextflow/seqera/04_setup_launchpad.md"

I'm about to head to the airport, but if you have time to review part 1 and/or open a PR into this branch that moves content from 10_seqera.md into the new structure I've outlined that would be much appreciated. <3

Comments on part 1, just a suggestion about how the config stuff is described.

Boarding plane now, will try more later if I can :-)

This is ready for review. I decided to stop after the first two sections as the "simulated slurm tower agent" idea I had for a hands-on teaching of compute environments just didn't seem right once I wrote it up. (It's stashed in #420 ).

For now, let's get these two sections in and come back later to that idea after we figure out how to run slum, grid engine or some other executor within a devcontainer.

I like the flow a lot, feels just right in terms of continuity with the previous parts. There are a few explanations that I felt could be clarified a little but I'm totally ok leaving that for an ulterior round. I didn't test it in practice yet but (what could possibly go wrong) it all seems really solid. Big thumbs up from me.

Great work, Ken! I left a few suggestions/comments.
