Chore upgrade kombu, celery, and redis and set max tasks to 100

[TessaIO]

Hi,
a bit of context about these changes:

• For version upgrades, it was mainly to solve a recurring issue that was happening, which was celery workers getting stuck because of redis restarts. These version upgrades fixed most of our issues on the production cluster.
• For the max-tasks-per-child, we noticed that the CPU on workers was always at the maximum, and thanks to this medium page, we found out that setting the number to 100 solved the issue. If you want to make it dynamic, I'm also down for that.

Probably fixes #1552
