In a recently installed cluster running 4.13.29, after configuring the cluster-wide-proxy, the "vsphere-problem-detector" is not taking the proxy configuration.
As the pod cannot reach vSphere  it's failing to run checks:
2024-02-01T09:28:00.150332407Z E0201 09:28:00.150292       1 operator.go:199] failed to run checks: failed to connect to vsphere.local: Post "https://vsphere.local/sdk": dial tcp 172.16.1.3:443: i/o timeout  

The pod doesn't get the cluster proxy settings as expected:
   - name: HTTPS_PROXY
     value: http://proxy.local:3128
   - name: HTTP_PROXY
     value: http://proxy.local:3128

Other storage related pods get the configuration expected as above.

This causes the vsphere-problem-detector to fail connections to vSphere, hence failing the health checks.

  4.13.29 

   Always

    1.Configure cluster-wide proxy in the environment. 
    2. Wait for the change
    3. Check the pod configuration
