Compaction concurrency is not respected for the same user #7298
Description
Describe the bug
When configuring concurrency to 1. compactors will run more than one compaction per compactor for the same user at the same time ignoring the concurrency configuration.
For example: 24h and 12h compaction at the same time.
This is surprising and can cause extra need of space in disks that is almost never used.
To Reproduce
- Configure compactor concurrency to 1 (Default)
- Use 2h,12h,24h blocks
- Put 6x2h blocks and 2x12 blocks in the bucket
- Watch the logs run compaction for both compaction levels at the same time
Expected behavior
it should only do one compaction at the time if concurrency is set to 1.
There should be an integration test for this
