Polishing Actually enable fat db pr (#1974) (#2048)

Browse Source 
* Actually enable fat db, and do RPCs for it.

* Implement HashDB traits for AccountDB.

* user defaults

* finished user defaults

* user defaults are network-dependent

* added tests for newly added functions, logger is initialized first

* dir cleanup in progress

* user_file is placed next to snapshots

* fixing requested change
