What do these changes do?

Well, celery is completely removed.
Also as celery is gone, there is no need for the Flower application anymore. Thus:
⚠️ devops: remove any entry with Flower in Ops.

🎉 long live to celery! Probably will see her back soon

Other changes (not in the description)

• adds settings_library to webserver's requirements
• using settings_lbirary.RabbitSettings as computation settings

[GitHK]

A few library upgrades slipped. Please remove them before merging.

[GitHK]

also this slipped through

[sanderegg]

I think this may be due to the fact that celery was blocking it before? @pcrespov

[GitHK]

that would also be my guess but I'd do all the upgrades separately in different PRs, as usual.

[sanderegg]

ok, no this is a new requirement coming with settings-library so I think that is ok.

[pcrespov]

I think this case is justified (since it was produce with a target upgrade) and there is no need to create a separate PR for it, provided all tests pass

[GitHK]

another click upgrade

[mguidon]

tada long live to celery! Probably will see her back soon

She? Now you confuse me. Hardware is female and software is male, no?
