cloud test fix: ServiceDeployment test fails occasionally

Test fails intermittently because dind container fails to come up.
The issue appears to be a docker problem where it tries to modify
iptables rules and gets error code 4, similar to this bug:
moby/moby#12547
Fix is to retry starting the container using restartPolicy.
