Hi all! There is a new feature: reconnect on open. It is useful when
start of vm and start of nbd server are not simple to sync.

This is based on "[PATCH 0/4] nbd reconnect new fixes"
Based-on: <20200903190301.367620-1-vsementsov@virtuozzo.com>

Vladimir Sementsov-Ogievskiy (3):
  block/nbd: move initial connect to coroutine
  nbd: allow reconnect on open, with corresponding new options
  iotests: add 306 to test reconnect on nbd open
