Noisy logging on server timeout

[benbariteau]

I'm seeing a lot of these:

Unhandled error in EventualResult
Traceback (most recent call last):
  File "/nail/home/bariteau/pg/repl-delay-update-daemon/venv/lib/python3.6/site-packages/twisted/internet/defer.py", line 567, in _startRunCallbacks

    "send the response".format(timeout=timeout)
fido.exceptions.HTTPTimeoutError: Connection was closed by fido because the server took more than timeout=None seconds to send the response

With code that looks like:

import fido
from crochet import TimeoutError

future = fido.fetch(
    'http://example.com/resource',
)
try:
    future.wait(timeout=1.0)
except TimeoutError:
    pass
finally:
    future.cancel()

While hitting a server that takes longer than 1 second to respond.

I don't expect this to timeout all the time, but it happens often enough that it's a problem.
