a17261038c Include tools CMakeLists in the top level CMakeLists
Summary:
Split main CMakeLists into src/CMakeLists

The main CMakeLists duty is to make all the required libraries and
variables visible to all of the other sub-CMakeLists. After doing that,
it should include those sub-CMakeLists according to configuration
options.

This should make global configurations easier to reuse without polluting
the global space with locally related configurations. It is a necessary
step for including other projects like 'tools' in the release
installation.

Building tools is automatically disabled, but can be enabled by setting
the TOOLS option to ON when running cmake. This should allow on demand
building as well as combined installation of Memgraph and its tools.

e26456d5ad Fix durability test flakyness
Summary:
It occurred that part of the durability flakyness test might be that the
same durability directory is used always. If the test is run
simultaneously on a single system, there will be interference.

This might not actually fix all the flakyness :(

I also made the `utils::RandomString` function since that's now used in
multiple places, tested it etc.

ce3638b25e Prepare transactional engine for distributed
Summary:
The current idea is that the same MG binary can be used for single-node,
distributed master and distributed worker. The transactional engine in
the single-node and distributed master is the same: it determines the
transactional time and exposes all the "global" functionalities. In the
distributed worker the "global" functions must contact the master.

5a41478789 Add maintainer scripts for DEB package
Summary:
Add postinst script for DEB package

The script creates a 'memgraph' group and sets permission on installed
'/var/*/memgraph' directories. Only the group is created, while
'memgraph' user is not. It seems more sane only to require group
membership for using memgraph.

Add conffiles for DEB package

This allows for `dpkg` to detect changes in configuration files and
present them to the user. Therefore, we don't need to care whether the
configuration merges are handled correctly nor if we accidentally
overwrite them.

Add postrm script for DEB packaging

The script is only used so that `dpkg --purge` removes '/var/*/memgraph'
directories, even if they contain something.

Add email, longer description and license file to DEB packaging, as well
as a systemd service.

Provide a logrotate configuration and support it in memgraph.

Use DEB package for Docker installation

This way, the whole installation process and testing should go through
DEB.

b7188c296c Fix CSV multiple edge file import
Summary:
The CSV importer used to generate non-unique edge IDs when

1e0ac8ab8f Write-ahead log
Summary:
My dear fellow Memgraphians. It's friday afternoon, and I am as ready to pop as WAL is to get reviewed...

What's done:
- Vertices and Edges have global IDs, stored in `VersionList`. Main storage is now a concurrent map ID->vlist_ptr.
- WriteAheadLog class added. It's based around buffering WAL::Op objects (elementraly DB changes) and periodically serializing and flusing them to disk.
- Snapshot recovery refactored, WAL recovery added. Snapshot format changed again to include necessary info.
- Durability testing completely reworked.

What's not done (and should be when we decide how):
- Old WAL file purging.
- Config refactor (naming and organization). Will do when we discuss what we want.
- Changelog and new feature documentation (both depending on the point above).
- Better error handling and recovery feedback. Currently it's all returning bools, which is not fine-grained enough (neither for errors nor partial successes, also EOF is reported as a failure at the moment).
- Moving the implementation of WAL stuff to .cpp where possible.
- Not sure if there are transactions being created outside of `GraphDbAccessor` and it's `BuildIndex`. Need to look into.
- True write-ahead logic (flag controlled): not committing a DB transaction if the WAL has not flushed it's data. We can discuss the gain/effort ratio for this feature.

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.

be16409da2 Harness MATCH tests refactored
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 :(

Summary: The previous version didn't seemt to be able to print the operator tree below the `Expand` operator. It seems it was unable to reach the `input_` field because it's a member of the `ExpandCommon` super-type. The proposed fix handles that. @teon, please test, verify, modify, whatever, just ensure printing works below `Expand` operators.

051c38acab Neo to Memgraph importer tool sketch added
Summary:
This importer is Bolt based. It loads data from Neo and directly injects into
Memgraph. Persistence is optional (JSON based). Currently it works for small
datasets, to make it work for larger datasets batching is required. For it to
work more efficiently indexing on label+property is required (in progress).

An in-Memgraph implementation of JSON importing could be much more efficient,
and is compatible with this script. This sript could be used for exporting
from Neo, and a C++ importer tool for the Memgraph side import.

I suggest that Gradicek takes this over and I can move on to other tasks
I have (if Gradicek is available for this).

Explicit loading of scripts can be done inside gdb by running
