Handling occupied port doesn't work when reuseaddr is enabled

[Lorak-mmk]

Driver has the following logic when using advanced shard awareness:

• Produce an iterator of port numbers to try to bind locally to.
• Iterate over it.
• For each port:
  • Try to open connection using this local port
  • If it works, great. If not, check if the error indicates that the port is occupied
  • If it is, try next port
  • If it is not, return the error

Turns out that when reuseaddr is enabled, a different error (AddrNotAvailable) is returned for occupied port, making adv shard awareness not resilient to occupied ports.
