Summary:
GraphDb is refactored to become an API exposing different parts
necessary for the database to function. These different parts can have
different implementations in SingleNode or distributed Master/Server
GraphDb implementations.
Interally GraphDb is implemented using two class heirarchies. One
contains all the members and correct wiring for each situation. The
other takes care of initialization and shutdown. This architecture is
practical because it can guarantee that the initialization of the
object structure is complete, before initializing state.

Summary:
No logic changes, just split `tx::MasterEngine` into
`tx::SingleNodeEngine` and `tx::MasterEngine`. This gives better
responsibility separation and is more appropriate now there is no
Start/Shutdown.

Summary:
`JailService` exposes jail API and knows how to
start and stop binaries. Every test should be
defined as python module with exposed
`run` method. Script `master.py` is used
for running tests and takes test module
name as argument. Machine IP addresses are
defined in environment variables. To run test
locally use `local_runner` script.

Summary:
A PropertyValueStore is not a generic data structure, but only ever used
to store properties in a Vertex/Edge. It has behaviours specific to it.
So, the templatization was not necessary.

Summary:
If there was no plan caching, the CachedPlan would not survive
`Interpreter::operator()`, as it was not owned by the
`Interpreter::Result`. If there was caching, it could hapen that the
cache got invalidated while that plan was being interpreted (by
another thread) without that interpretation retaining ownership.
Also simplified code around this.

Not having a virtual destructor caused tests
to fail (cypher_main_visitor, interpreter) sporadically
since unfreed memory was re-used incorrectly.
Also Valgrind complained constantly.

Summary:
This is a proposal on how the WAL recovery process can be implemented so
that Deltas aren't accumulated, but instead applied in the same order
they are written to the WAL.
I *believe* that the only additional requirement on the system are
atomic transaction Begin/Commit/Abort. By atomic I mean that they are
present in the WAL in exactly the same ordering like in the transaciton
engine, to ensure the same commitability of original and recovery
transactions.
This could be a requirement for HA recovery. It is desirable that WAL
and HA log become the same thing, and the recovery process too.

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
