adding opts for WatchFunc in informers

[ccding]

I used kubebuilder to create an operator framework and wanted to modify TimeoutSeconds in the listerwatcher of informers. I dug into the controller-runtime code and found we should set TimeoutSeconds in this line of code

controller-runtime/pkg/cache/internal/informers.go

Line 357 in 27afc15

return listWatcher.WatchFunc(opts)

However, I didn't figure out if there was a way to pass a config in. Does anyone happen to know if there is a workaround?

I created a PR: #2738

please let me know if there is any issues. Thanks
