Update resource allocation for all Nomulus GKE deployments (#2796)

ALl deployments received update to averageUtilization cpu. This should allow us to stay ahead of the curve of traffic and create instances before we cpu reached the limit.
Frontend cpu allocation has caused "noise neighbors" problem with pods assigned to nodes where there's not enough bursting capacity, so I increased it.
Adjusted rest of the deployments according to their utilization.
