feat(db-*): return database name to unsanitized config (#11913)

You can access the database name from `sanitizedConfig.db.name`. But
currently, it' not possible to access the db name from the unsanitized
config.

Plugins only have access to the unsanitized config. This change allows
db adapters to return the db name early, which will allow plugins to
conditionally initialize db-specific functionality
