Add Resource to the deployment

[timrhomberg]

When a new Kubernetes Image Puller is created, the deployment, doesn't have resources assigned. But this is necessary when resource quotas are applied in ocp.

Two possible solution:

1. Automatically assign some resources e.g.
   resources:
   requests:
   cpu: '0.2'
   memory: '100Mi'
   limits:
   cpu: '0.2'
   memory: '100Mi'
2. Assign the resources as a parameter when creating a Kubernetes image puller instance e.g.
   DeploymentRequestsMemory
   DeploymentRequestsCPU
   DeploymentLimitsMemory
   DeploymentLimitsCPU
