Subject: [PATCH 5/6] Add configurable scheduling options to
 gpu-process-exporter chart

Added support for custom tolerations, affinity, and topologySpreadConstraints to allow the GPU exporter to work with cluster-specific taints and scheduling requirements. The hard-coded nodeSelector and tolerations have been moved to configurable defaults in values.yaml, maintaining backward compatibility while providing flexibility for custom cluster configurations.

Changes:
- Bump chart version from 1.0.1 to 1.1.0
- Move hard-coded nodeSelector to values.yaml with backward-compatible defaults
- Move hard-coded tolerations to values.yaml with backward-compatible defaults
- Add affinity configuration support
- Add topologySpreadConstraints configuration support
- Update daemonset template to use configurable scheduling values
