This takes advantage of go-ds-badger "auto-gc" feature. It will run a GC cycle made of multiple GC rounds (until it cannot GC more) automatically. The behaviour is enabled by default in the configuration and can be disabled by setting "gc_interval" to "0m". Hopefully this prevents badger datastores from growing crazy.
