Juan Miguel Olmo Martínez 0db62c86d2 Allow to launch pods when memory request is set (but no memory limit) in cluster CRD file
With this change the memory limit is only checked if it has been set
explicitely in the cluster CRD file.
This allow the pod to be created following the Burstable QoS strategy.

Before this change an error was raised (error trying to get the memory
limit) in the spec.CheckPodMemory function and the pod with only a 'memory request' set, was not able to start.

Resolves: #3564
