socket.timeout error when submitting image using `evalai push`

[RishabhJain2018]

When submitting a new docker image for the 1st time I often get the following error:

$ evalai push objectnet_dmayo:v3--phase objectnet-objectnet-express-293

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/urllib3/response.py", line 362, in _error_catcher

    return self._sock.recv_into(b)

During handling of the above exception, another exception occurred:

Repeating the push immediately after is usually success - presumably because most of the docker layers have been cached at the server.

Things already tried and didn't work-

1. Maybe setting DOCKER_CLIENT_TIMEOUT will help: docker/compose#6837
2. Tried setting following env vars:

DOCKER_CLIENT_TIMEOUT=600
COMPOSE_HTTP_TIMEOUT=600

3. Also tried setting following in /etc/docker/daemon.json

    "max-concurrent-uploads": 1,

@Ayukha Can you please look into this?

[Ayukha]

@RishabhJain2018 sure

One more thing, the docker images that gave this error was of around 7.5 GB in size.
