Add configuration for each Log Storage

[jopemachine]

Now that users can choose from various log storages, the configuration should allow for setting options specific to each storage.

For example, in the previous code, you could modify settings like Config.lmdb_map_size, but when using RocksDB, fields like lmdb_map_size should no longer be configurable. Instead, only the fields relevant to RocksDB should be exposed.
