Summary:
In preparation for distributed storage we need to have labels/properties/edgetypes uniquely identifiable by their ids, which will be global in near future.
The old design has to be abandoned because it's not possible to keep track of global labels/properties/edgetypes while they are local pointers.

Summary:
Looking for connected components in a random graph. This test performs the following:
- Generates a random graph that is NOT sequential in memory (otherwise itertion over edges is 2 or more times faster).
- Connectivity by iterating over all the edges.
- Ditto over vertices.
- Ditto over vertices in parallel.
Not done:
- Edge filtering based on XY. I could/should add that to see how it affects perf.
- Getting component info out from union-find.
Local results are encouraging. Iterating over the graph is the bottleneck. Still, I get connectivity of 10M vertices/edges in <7sec (parallel over vertices). Will test on 250M remote now.
Locally obtained results (20M/20M, 2 threads)

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.

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:
We need to explicitly say that UNION clause isn't supported, otherwise
it gets silently ignored. So for example, `CREATE () UNION CREATE ()`
would create 2 nodes without a hitch. On the other hand,
`RETURN 1 UNION RETURN 2` would complain that there is more than 1
RETURN in the query, which was misleading.

Tests have been updated to catch this error and other behaviour. Other
than this change, `AND` should behave as before.

Summary:
Use sigaction to register signal handlers.
This is preferred over `signal` function, according to `man 3p signal`.
Add global sig_atomic_t flag when shutting down.
Block other signal handlers when shutting down.

Summary: Old code would start reactor thread first, and then try to insert it in unordered_map. If it failed to insert it, the thread handler would get destructed with thread still running, which raises an exception.
