Mentat

Bsddb3 library is deprecated and it is recommended to switch to berkeleydb.

1st possible solution: switch to berkeleydb
Bsddb3 PyPI page describes what needs to be done in order to migrate to berkeleydb.

2nd possible solution: remove it altogether
This would require removing the module mentat.services.cache.py (the only module which uses bsddb3) and rewriting mentat.plugin.enricher.passivedns (the only module which uses mentat.services.cache.py) in a way it won't use caching anymore.

Part of mentat.plugin.enricher.passivedns is for The Email Laundry (EML) , which no longer exists, so this part should also be removed.
