c68ed8d94e Add implementation of synchronous replication (#7) 
This implements the initial version of synchronous replication.
Currently, only one replica is supported and that isn't configurable.

To run the main instance use the following command:
```
./memgraph \
    --main \
    --data-directory main-data \
    --storage-properties-on-edges \
    --storage-wal-enabled \
    --storage-snapshot-interval-sec 300
```

To run the replica instance use the following command:
```
./memgraph \
    --replica \
    --data-directory replica-data \
    --storage-properties-on-edges \
    --bolt-port 7688
```

You can then write/read data to Bolt port 7687 (the main instance) and also you
can read the data from the replica instance using Bolt port 7688.

NOTE: The main instance *must* be started without any data and the replica
*must* be started before any data is added to the main instance.

* Add basic synchronous replication test
* Using RWLock for replication stuff

9c095501d8 query/procedure: Add type system for Cypher 
Summary:
The type system is modelled after "CIP2015-09-16"
https://github.com/opencypher/openCypher/blob/master/cip/1.accepted/CIP2015-09-16-public-type-system-type-annotation.adoc

This is needed for registering procedures and their signatures. The
users will be able to specify what a custom procedure accepts and
returns. All of this needs to be available for inspection during
runtime. Therefore, this diff implements printing types as a user
presentable string. In the future, we will probably want to add type
checking through these types, because openCypher requires type checking
on values passed in and returned from custom procedures.
