Increase renovate concurrent MR limit
I would like to try to increase the number of concurrent MR that renovate can open.
I understood that allowing multiple MR for renovate would result in a lot of CI pipelines runs and would prevent others users to use the CI:
- open MR 1,2,3 => CI runs for 1,2,3
- automerge MR 1 => CI runs for develop
- rebase 2,3 => CI runs for 2,3
- automerge MR 2 => CI runs for develop
- rebase 3 => CI runs for 3
So a lot of CI cycles.
Maybe we can work around this by having a dedicated runner (a low priority one) for any changes made by renovate. It would prevent from blocking the CI for others, and we could let it run in background, doing it's job on it's own, slowly.
