[TASK] Replace jobq lib with an alternative way for listing remote backup volumes and info

## What's the task? Please describe

For now, we are using `github.com/honestbee/jobq` for queries backup volumes & each backup info, but that lib lacks an OSS license. So, we need to look for an alternative solution.
