Summary:
Integrated kafka library into memgraph. This version supports all opencypher
features and will only output messages consumed from kafka.
Depends on D1434
Next steps are persisting stream metadata and transforming messages in order to
store them in the graph.

Summary:
This binary is installed and packaged for release. This is just a quick
solution for releasing the Community 0.10 version. We still need to
setup the installation and packaging for both the Enterprise and
Community versions. Additionally, the automated build system needs to
test both binaries for correct behaviour. Obviously, some tests can only
be run on one of the 2 versions.

Summary:
Although the first solution used cereal, the final implementation uses
boost. Since the cereal is still used in the codebase, compilation has
been modified to support multithreaded cereal.
In addition to serializing Ast classes, the following also needed to be
serialized:
* GraphDbTypes
* Symbol
* TypedValue
TypedValue is treated specially, by inlining the serialization code in
the Ast class, concretely PrimitiveLiteral.
Another special case was the Function Ast class, which now stores a
function name which is resolved to a concrete std::function on
construction.
Tests have been added for serialized Ast in
tests/unit/cypher_main_visitor

Summary:
When developing or having local fixes to various libraries, running
libs/setup.sh would delete all of those changes. This is now changed, so
that libs/cleanup.sh isn't run at the start. In addition to that, all of
the libraries cloned from git will stash local changes and reapply them
after checking out the desired commit. Conflicting changes should cause
an error and stop the script from continuing.

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:
This is probably a bug in CMake. When the external projects are forced
to be rechecked, CPack takes their outputs and puts them in binary
release.
Since rechecking is removed, this means that any changes to external
projects (like gflags or glog) will not be recompiled with plain
`make all`. You need to call `make clean` first. The same applies to
catching configuration like removal of filenames in glog when creating a
release build.

To use the library in code, do the following.
* Include glog, `include "glog/logging.h"`
* Initialize logging from a main entry point,
`google::InitGoogleLogging(argv[0]);`
* Log anywhere from your code, `LOG(INFO) << "Hello world from glog";`
For advanced use, refer to glog's documentation.

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.
