expose connect_timeout on HTTP remote

[palenge]

Hi!
We have a HTTP remote, when we upload dig files we get connection timeout. There is any way to expose this property already exposed on S3?

This timeout means, that uploads need to finish in 60 seconds, causing major problems when using http remote to upload larger files. The timeout in our environment causes the upload to stop after 60 seconds, as until the upload is finished no response is send back to the client, causing a read-timeout. Please remove this timeout (set value to None), or make it possible, to set this through a setting on the dvc remote config, and/or through a environment variable.

@cklukas Hi. That's not exactly how it works. sock_read sets the timeout for receiving data on the socket, meaning that if no data is received for 60s, the socket is forcefully closed (e.g. see aiohttp docs here: https://docs.aiohttp.org/en/stable/client_quickstart.html#timeouts).

I do agree that there's some issue with timeouts and we'll be working to expose timeout options to avoid this kind of problems.
