59bc9d8989 Fix label/edge/property name escaping in DUMP DATABASE
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`)
```

6f83fff171 Implement durability functionality for unique constraints
Summary:
This diff contains a necessary functionality to save and restore unique
constraint operations. The previous snapshot/WAL version is backward
compatible. Integration tests for migration from older snapshot and WAL
versions are also included.
