feat: add configurable health probes for controller and node components

[vagharsh]

This PR adds configurable probe support for both controller and node components while maintaining backward compatibility.

Changes

• Add configurable livenessProbe, readinessProbe, and startupProbe settings for controller
• Add configurable livenessProbe, readinessProbe, and startupProbe settings for node
• Maintain backward compatibility by using existing hardcoded values as defaults
• Enable optional readiness and startup probes that can be configured independently
• Support all standard Kubernetes probe configuration options

Backward Compatibility

• Existing deployments continue to work without any changes
• Default probe configurations use the same values that were previously hardcoded
• Readiness and startup probes are optional and only enabled when explicitly configured

Testing

• Verified templates render correctly with default values
• Tested with custom probe configurations
• Confirmed backward compatibility with existing values

Hi @vagharsh. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
