Add automated test for Raft Summary: Created a new integration test for Raft protocol. The tests iterates through the Raft cluster and does the following: * kill machine `X` * execute a query * bring `X` back to life The first step is to insert a vertex in the cluster, and last step is to check if the cluster has all the data. I also edited some of the raft core files because this test surafaced some bugs. The `tester` binary is a hacked version of the HA client and so are the parts in the code that refuse to execute a query is the machine is not in `Leader` mode.o Those parts will go away once we have a proper HA client. I've run the `runner.py` for a while (215 times) ``` while ./runner.py &> log.txt; do echo -n "."; done ``` and it didn't break.

Include HA client in HA basic integration test Summary: - Included HA client - Fixed log messages to be 1-indexed - Added id properties to created nodes for easier debugging - Create and check steps are now executed 20 times each Reviewers: msantl Reviewed By: msantl Subscribers: pullbot Differential Revision: https://phabricator.memgraph.io/D2111 2019-06-04 21:18:30 +08:00			`"election_timeout_min": 750,`

Add replication timeout in Raft Summary: Added a new config parameter, replication timeout. This parameter sets the upper limit to the replication phase and once the timeout exceeds, the transaction engine stops accepting new transactions. We could experience this timeout in two cases: 1. a network partition 2. majority of the cluster stops working Reviewers: ipaljak Reviewed By: ipaljak Subscribers: pullbot Differential Revision: https://phabricator.memgraph.io/D1893 2019-02-27 21:20:30 +08:00			`"replication_timeout": 10000,`
