curb flakes in integration tests

instead of searching the fedora registry which is error prone, we instead search a local registry for the empty set search.

when running two containers with the same IP, i suspect the first container has not fully gotten its ip information back from cni when the second container fires.  rework this test such that we use nginx to make sure the container is up and running before continues which should pace the subsequent test.
