kibana: increase resource limits again

[NicoK]

I had to increase the memory requests and limits again because with the current resource limits, I cannot get Kibana deployed successfully on Azure. The following error occurs:

  Warning  FailedPostStartHook  15m (x3 over 17m)  kubelet, aks-nodepool1-38276290-vmss0000ap  Exec lifecycle hook ([bash -c #!/bin/bash

(Elasticsearch was up in both tests and Kibana immediately came up with the proposed settings but went into a CrashLoopBackOff with the current ones)
