e2e: network tiers should retry on 404 errors

Browse Source 
The feature is still Alpha and at times, the IP address previously used
by the load balancer in the test will not completely freed even after
the load balancer is long gone. In this case, the test URL with the IP
would return a 404 response. Tolerate this error and retry until the new
load balancer is fully established.
