tarantool asyncio connector

Tarantool connection driver for work with asyncio

Connector required tarantool version 1.6:

$ pip install aiotarantool

Also, you need to install tarantool-python for python 3 from github:

$ pip install git+https://github.com/tarantool/tarantool-python.git@master

Try it example:

import asyncio
import aiotarantool

cnt = 0

@asyncio.coroutine
def insert_job(tnt):
    global cnt

    for it in range(2500):
        cnt += 1
        r = yield from tnt.insert("tester", (cnt, cnt))

loop = asyncio.get_event_loop()

tnt = aiotarantool.connect("127.0.0.1", 3301)
tasks = [asyncio.async(insert_job(tnt))
         for _ in range(40)]

loop.run_until_complete(asyncio.wait(tasks))
loop.run_until_complete(tnt.close())
loop.close()

Under this scheme the aiotarantool driver makes a smaller number of read/write tarantool socket.
