Quiet socket.timeout: timed out

[lrivallain]

socket.timeout are raising traceback: quiet them by catching the error:

Traceback (most recent call last):
  File "XXXlib/python3.7/site-packages/amqp/transport.py", line 125, in _connect
    host, port, family, socket.SOCK_STREAM, SOL_TCP)
  File "/usr/lib/python3.7/socket.py", line 748, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -9] Address family for hostname not supported

During handling of the above exception, another exception occurred:

Same for :

    s = recv(n - len(rbuf))
ConnectionResetError: [Errno 104] Connection reset by peer

looks like it could be managed in kombu/mixins.py:

157c157
<         warn(W_CONN_ERROR, interval, exc, exc_info=1)
---
>         warn(W_CONN_ERROR, interval, exc, exc_info=0)
175c175
<                 warn(W_CONN_LOST, exc_info=1)
---
>                 warn(W_CONN_LOST, exc_info=0)

With this change: not traceback is printed: only logger.
