Summary:
This diff fixes the issue for label name (and edge type/property)
with spaces and special characters to avoid possible OpenCypher injections.
Consider an example where label name is 'hello :world'. `DUMP DATABASE`
used to return query which creates a node (u:hello :world) - i.e. node
that contains two labels 'hello' and 'world'. This fix escapes names to
create the following node with exactly one label as expected:
```
(u:`hello :world`)
```

Summary:
The storage now uses a file in the data directory (`.lock`) to determine
whether there is another instance of the storage running with the same data
directory. That helps notify the user/administrator that the system is running
in an unsupported configuration.
