Auto-reconnect does not work about asynctnt

[igorcoding]

Thank you for the report, but it's actually an intended behaviour. The main idea is that it's better to fail if connection is lost than hang the request trying to connect indefinitely to Tarantool. Take a look at the following script:

import asyncio
import asynctnt
import asynctnt.exceptions
import uvloop
asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())


async def run():
    c = asynctnt.Connection(host='localhost', port=33301)
    await c.connect()
    while 1:
        try:
            print(await c.call('box.info'))   # <-- Tarantool instance goes down here
        except asynctnt.exceptions.TarantoolNotConnectedError:
            print('lost connection')
        await asyncio.sleep(1)


loop = asyncio.get_event_loop()
try:
    loop.run_until_complete(run())
except KeyboardInterrupt:
    loop.stop()
    loop.close()

If you run it you will see messages like

Connect to Tarantool[localhost:33301] failed: ConnectionRefusedError(111, 'Connection refused'). Retrying in 0.333333 seconds

as asynctnt will try to reconnect to Tarntool in the background.And finally when you start Tarantool instance back it will continue to successfully execute call statements.

I get it. Sorry for bothering.
