feat(chart): supporting nodeSelector and tolerations

[caiofralmeida]

This pull request adds support for customizing node scheduling for the controllerManager deployment in the kube-startup-cpu-boost Helm chart. Users can now specify nodeSelector and tolerations in the values file to control which nodes the controller pods are scheduled on and which taints they tolerate.

Helm chart enhancements for pod scheduling:

• Added support for nodeSelector and tolerations in the controllerManager section of values.yaml, allowing users to specify node selection and taint toleration preferences.
• Updated the deployment.yaml template to include the nodeSelector and tolerations fields when provided, enabling the new configuration options in the rendered deployment manifest.
