Summary:
PushQueue with concurrent lock-free pushing, and single-threaded deletion. Iteration without modification can also be concurrent. Deletion should NOT be concurrent with iteration and other deletions, but can be concurrent with pushing.
There is no const iteraton at the moment, we can add it when necessary. Also I've not handled std::iterator_traits, might be fun getting into that :D

Summary:
CMake is smart enough to transitively detect dependencies and link them
appropriately. Therefore, it is enough that we put all libraries that
memgraph uses to the dependency list of memgraph_lib and memgraph_pic
targets.
Patch the fmt library for C++14 and higher
fmt library would detect that C++11 is supported and then put the
compiler flag. This flag was set so it overrides parent project compiler
flags. This override from fmt would prevent us from using C++14
features. New version (3.1) of fmt resolves this issue, but it hasn't
been released yet. Therefore, this commit updates the script which
clones fmt to use the released 3.0.1 version and apply the fix on that.

Summary:
Jenkins would hang at a random time while running all the tests.
The reason for that is a bug in skiplist implementation.
Skiplist method find_or_larger was never ending and would continuously stay in the while loop because the next node (with the queried value) onto which it would try to jump would be marked as deleted and that would stop it from jumping on it, or ending on that node.

Summary: Bolt PullAll works. ChunkedBuffer is implemented by the specification (the tests can be found in the tests/unit/bolt_chunked_buffer.cpp). Bolt session states method are refactored (all run methods have only one argument - active Session). Modifications related to the style guide.

Summary:
Add join function to functions.cmake
This is a convenience function which will join a list of values by
replacing ';' with the given separator.
cmake: Add fetching compile flags in gcc format
This is a utility function which takes all target compilation flags that
can be passed to gcc or clang.
Generate flags for PlanCompiler via cmake
Cmake will now collect all compiler options and definitions which are
then stored in a generated `query/plan_compiler.hpp`. The generated file
is not tracked by git and is stored inside cmake's build directory. The
file is fast to generate and may change often depending on the build
type.
Additionally, link and include directories are also generated as
absolute paths. In the future, we may want to support relative paths so
that copying/installing the build dir creates runnable binaries.
Add -Wall flag for all build types
Lowercase #pragma once in tests for network_common
It seems 'once' may be case sensitive, since clang outputs a warning for
it that the pragma is unknown.

DbAccessor:
-Guarantees that access to Vertex and Edge is possible only through
Vertex::Accessor and Edge::Accessor.
-Guarantees that changing Vertex and Edge is possible only using
Vertex::Accessor returned by vertex_insert() method and
Edge::Accessor returned by edge_insert() method.
-Offers CRUD for Vertex and Edge except iterating over all edges.
Squashed commit messages:
First step in database accessor refactoring done.
It's compiling.
All tests with exception of integration_querys pass
Tests now initialize logging facilities.
Refactored accessors.
