In this pull request, snapshot generation in pathdb has been ported from the legacy state snapshot implementation. Additionally, when running in path mode, legacy state snapshot data is now managed by the pathdb based snapshot logic. Note: Existing snapshot data will be re-generated, regardless of whether it was previously fully constructed.
