Summary:
In order to add kafka benchmark, `memgraph_bolt.cpp` has been split.
Now we have `memgraph_init.cpp/hpp` files with common memgraph startup code.
Kafka benchmark implements a new `main` function that doesn't start a bolt
server, it just creates and starts a stream. Then it waits for the stream to
start consuming and measures the time it took to import the given number of
entries.
This benchmark is in a new folder, `feature_benchmark`, and so should any new
bechmark that measures performance of memgraphs features.
