feat(cli): add renku rollback command

[Panaetius]

closes #2351
closes #440

adds a renku rollback command. The user gets presented with a (paginated) history of renku actions and can pick a point in time to return to, they are then shown all entities and files that would be changed by this action and, if they confirm, the repo is reset to that state.

Also removes the need for most renku commands to create multiple commits (with the exception of migrations).

Can be tested in https://renkulab.io/projects/ralf.grubenmann/test-rollback

Command to run: renku rollback

+1 on the PR description 😻

This looks great @Panaetius - just a few quick observations:

1. why no commit sha in the listing?
2. what happens if the number of commits/renku commands is very long?
3. a wording suggestion - since you say at the top "The following changes would be done" you can omit "that would be" from the lines that follow
4. this needs colors and emojis 😆

Well I thought if we ever allow running renku commands without commit (i.e. you have to explicitly commit once you're happy) we wouldn't have one. But at the moment we can add it, might be useful.

2. what happens if the number of commits/renku commands is very long?

it starts paging after 50 entries (you press 'm' to show the next 50), in a lazy way (so we don't have to parse the whole commit history every time the command is run).

3. a wording suggestion - since you say at the top "The following changes would be done" you can omit "that would be" from the lines that follow

👍

Hmm good point regarding the sha. How would this work if commands were not tied to commits? I guess we would make a new commit that would undo whatever had been done? Or we would revert to a commit before the command in question? In the latter case, having the commit sha would still be useful since it would allow the user to quickly place the command in the broader context. The emoji suggestion was mostly a joke, but I like 🔥 😄

Hi @Panaetius I'm currently testing the repo out - I've run into a bug - I can't seem to fetch datasets

and when I try to add datasets from the UI:

Is there any way I can remedy this in this repo?

[Panaetius]

@gavin-k-lee You can't use that project on renkulab, it uses renku-python version 1.0.0 and is not supported by the current version of renkulab.

You should be able to start an interactive session and work there (the Dockerfile is set up to use this branch) or clone it locally, install this branch and work there.

Looking good so far! It might be the browser but the bin emoji doesn't show for some reason

[Panaetius]

@gavin-k-lee The garbage bin? I didn't want to spam emojis and just added the flame

[gavin-k-lee]

Oh right ok.

[rokroskar]

This looks good (apologies for taking a while to re-review)!

This actually also (at least partially) closes #440 and #338

[vigsterkr]

why define twice this static var? see in renku/cli/rollback.py above CHECKPOINTS_PER_PAGE = 10
