SSHLibrary non-configurable timeout for scp

scp.py has a default but configurable timeout of 10 seconds: https://github.com/jbardin/scp.py/blob/master/scp.py#L103

In our case this is sometimes too short. Our ssh server takes a long time to reply to the connection request (probably because of misconfigured DNS causing DNS lookup timeouts). As a result we get a timeout error.

This timeout does not seem to be configurable without modifying sshlibrary. The connection timeout (used for Read Until) is not forwarded to scp.py, and there is no other way to set it (I don't know if it makes sense to use the same timeout). Only the transport is passed to the SCPClient constructor: https://github.com/robotframework/SSHLibrary/blob/master/src/SSHLibrary/pythonclient.py#L394

Does it make sense to reuse the timeout from the connection configuration for this? If that's appropriate, I think the fix would be reasonably easy to do.
