Summary:
This diff splits single node and distributed storage from each other.
Currently all of the storage code is copied into two directories (one single
node, one distributed). The logic used in the storage implementation isn't
touched, it will be refactored in following diffs.
To clean the working directory after this diff you should execute:
```
rm database/state_delta.capnp
rm database/state_delta.hpp
rm storage/concurrent_id_mapper_rpc_messages.capnp
rm storage/concurrent_id_mapper_rpc_messages.hpp
```

Summary:
Added WAL and Snapshot explorer utility executables that read a wal or a
snapshot file and print the content of it, but the main purpose is that they
check it.
This is useful when debugging durability and want to know where it gets stuck.
