Add ResourceLimits for test pods
Browse files Browse the repository at this point in the history 
The test pods spawned by the test operator prior to this change were
executed without any resource limits. This ultimately meant that the
pods could consume an unlimited amount of resources until the limit for
a worker node was reached.

This commit introduces default resource limits for each test pod
spawned by the test operator (tempest, tobiko, ansibletest, horizontest
pod). The default value can be overridden using .Spec.Resources
parameter which is introduced as part of this commit as well [1]:

spec:
  resources:
    requests:
      memory: 1Gi
      cpu:    250m
    limits:
      memory: 2Gi
      cpu:    500M
