Integrate pruning config into static file and database service

[Rjected]

Currently the static file and database service are not aware of any pruning configuration. There is a pruning-related method, but it just runs to completion. Additionally, both components might need to be aware of pruning. We need to write basic tests which use an existing pruning config, runs some common methods using the PersistenceHandle, and checks that certain data was properly pruned, or not written altogether.
