Summary:
- Removed durability::Summary because it was wired into reader and stopped me from recovering WAL files.
- Refactored and renamed BufferedFile(Reader/Writer) to HashedFile(Reader/Writer).
- Vertex and edge counts in the snapshot are now hashed.
Breaking snapshot compatibility again (hashing), but since the previous version was not released, and we are not caching snapshots, the previous version does not need to be supported.

Summary:
New snapshot structure:
- magic number
- snapshot version (old-version recovery not yet implemented)
- transaction snapshot (will be used in the WAL)
- the rest is as before (indices, vertices, edges)
Not backward compatible with the old snapshotting.
Does not improve error handling (user feedback). A task for that has been added.

Summary:
Since we have different kind of workers in Apollo we should pass
assigned cpus to harness from apollo generate script and not define them

Summary:
C++ implementation of CSV to Memgraph's snapshot file is much more efficient then
the Python implementation. It includes a huge part of the Memgraph's source
code and the code has to be compiled (which is not easy). Because of that it
has to be packaged.

Summary:
Setup scaffolding for building Memgraph tools.
Change `utils::Split` without delimiter to split on whitespace.
This should make `Split` behave just like Python's `str.split`, which is
more practical for splitting on word boundaries.
Add `utils::StartsWith` function.
Rewrite csv_to_snapshot to C++.

Summary:
1. Test setup rewritten to take cca 8 seconds. Note that edges are created by using:
`MATCH (a) WITH a MATCH (b) WITH b WHERE rand() < X CREATE (a)-[:ET]->(b)`
Where `X` is a threshold calculated so the desired edge count is the expectation. This seems the only feasable way of generating a large number of edges since query execution does not depend on edge count, but on vertex count.
2. Using the new `assert` function to verify graph state. I recommend doing that in all the harness tests (I don't think we currently have something better).
3. All tests rewritten to take around 200ms per iteration.
4. Test are using SKIP to avoid sending data to the client, but ensure that appropriate operations get executed. This currently seems like the best way of removing unwanted side-effects.
Harness will cost us our sanity. And it doesn't even provide good quality regression testing we really need :(
