Revert "Workaround for process_start_time_seconds metric fix" after upgrading component-base library #69
Description
The current process_start_time_seconds does not work because a bug in the component-base library. The fix is here:
kubernetes/kubernetes#96435
But that can take pretty long time before we can upgrade the dependency. So until then, we can use the workaround #68 to fix that.
This issue is to track that we need to revert this workaround back after we upgrade the dependency.
