Add primary node discovery
3124d33 
Early versions of tests always first node as a primary in a cluster.
With automated leader election leader can be on any node in clustera,
so discovery of primary instance has been added.

It consists of SQL function `_LEADER()` implemented in Lua,

```
unix/:/var/run/tarantool/jepsen.control> box.execute([[SELECT _LEADER()]])
---
- metadata:
  - name: COLUMN_1
    type: string
  rows:
  - ['89.208.84.154']
...
```

`primary` function that connects to desired node and gets IP address of primary
instance using `_LEADER()` function and `primaries` function that gather
information about primaries on every node in a cluster.

Closes #43
Closes #17
