runGarbageCollection

Removes all sync metadata for any remote peers which aren't currently connected. This method shouldn't usually be called. Manually running garbage collection often will result in slower sync times. Ditto automatically runs a garbage a collection process in the background at optimal times.

Manually running garbage collection is typically only useful during testing if large amounts of data are being generated. Alternatively, if an entire data set is to be evicted and it's clear that maintaining this metadata isn't necessary, then garbage collection could be run after evicting the old data.
