We notice that the ephemeral pods spun up by CI stages are not evenly spread across 3 AZs. Upon checking, we want to add topologySpreadConstraints into spec against the topologyKey: topology.kubernetes.io/zone which will help achieve a more even spread

CUrrently Harness doesnt support to add "topologySpreadConstraints" in build pod. We need to be able to add the spec "topologySpreadConstraints" in build pod so can get the build pods scheduled across nodes in multiple AZs
