Summary:
Added a warning to the log. Every 3 seconds (let's not make that configurable). Can be turned off.
I still don't like this. We are raising another thread and reading a file to do monitoring. We're developing a DB, not a sys monitor. Serious admins do that themselves. But, here it is.
UPDATE:
Cleaned up `utils/sysinfo/memory`. Removed all unused functions. Removed the faulty memory check in `tests/concurrent`.

Summary:
- Keys() functions in the indices can't be const because ConcurrentMap doesn't provide const accessors (and they are broken in skiplist) :D
- no cucumber tests because many tests create indices so it's hard to say what's inside and what not

Summary: `assert` function added. Useful to us for asserting DB state in harness tests. Potentially useful to the client for breaking out of a query as soon as a predicate fails, as opposed to collecting result and checking them client-side.

Summary:
Added:
- map support in PropertyValue
- conversion of map TypedValue to PropertyValue if appropriate flag is set (undocumented because it's private)
- ordering of map PropertyValue in LabelPropertyIndex
- issue raised regarding list and value property modifications in storage (currently unsupported)
Maybe I missed some feature or whatever?

Summary:
- added only one function for getting the total (in + out) vertex degree, it's required for the Ravelin use-case
- specific `degree_in` and `degree_out` functions can be added as necessary
- also fixed random_graph_generator bug (needed it for testing)

Summary:
A lot of style changes. Major content changes are the following:
- Bolt and "interface" stuff moved to quick-start (not so quick anymore?)
- removed the "Memgraph is 100% Bolt compliant" and client-compatiblity claims because they are probably not true and aren't necessary
- moved "Limitations" to the bottom
- Python quickstart - moved explanations into the code, moved DB cleanup to the end (natural data flow)
What still needs work in my opion:
- the table in the "Limitations" part renders horribly (no space between cells)
- heading3 and heading4 are rendered the same in the "QuickStart", which is bad in the "Limitations" section
- I only went through the "Installation" and part of the "QuickStart", still a lot to go

This is a basic overview of various supported features of openCypher in
Memgraph. A lot of the documentation refers to Neo4j manual. This needs to
change in the future.
