Retry the integration setup on connection error

Sometimes there are network errors communicating with pypi
during a long running (1h+) integration gate job. This
causes the job to fail, and wastes a lot of time re-running
the job to get it to pass. This change makes it less likely
to fail, as if there is a timeout or socket error, the
integration setup will retry.
