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:
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:
What's done:
- `RecordAccessor` can represent remote data
- `GraphDbAccessor` manages remote data
- Cleanup: different `EdgeAccessor lazyness (@dgleich: take a look), unused methods, documentation...
- `TODO` placeholders for remote implementation
What's not done:
- RPC and data transfer
- how exactly remote errors are handled
- not sure if any MVCC Record info for remote data should be tracked
- WAL and RPC Deltas properly handled (Gleich working on extracting `Wal::Op`)
This implementation should not break single-node execution, and should provide good abstractions and placeholders for distributed. Once that's satisfied, it should land.

Summary:
Parsing query with string values wasn't correct. It didn't matter
with which type of quote mark string value started. It simply took
any possible quote mark which wasn't escaped as possible beginning
or end for string value.
Following example didn't work:
{name: "Chris Anderson: Technology's long tail"}
Detected string value was "Chris Anderson: Technology' and because
of that query broke. Now, string is detected by memorizing which
quote mark was used to start parsing string value and is required
to end string value with that quote mark.

It occurred that part of the durability flakyness test might be that the
same durability directory is used always. If the test is run
simultaneously on a single system, there will be interference.
This might not actually fix all the flakyness :(
I also made the `utils::RandomString` function since that's now used in
multiple places, tested it etc.

Summary:
This change generates multiple PropertyFilters for expressions such as
`n.prop1 = m.prop2`. When choosing one PropertyFilter, we want to also
remove the other one, because they represent the same original
expression. Therefore, the removal is no longer based on FilterInfo
equality, but on the original expression equality. Additionally,
FilterInfo and PropertyFilter equality operators have been removed to
avoid any pretense they do what you expect or want.

Summary:
The current idea is that the same MG binary can be used for single-node,
distributed master and distributed worker. The transactional engine in
the single-node and distributed master is the same: it determines the
transactional time and exposes all the "global" functionalities. In the
distributed worker the "global" functions must contact the master.
