It is recommended to adjust the SidecarSet resource to the namespace level. 建议将 SidecarSet 资源调整为命名空间级别

What would you like to be added:
SidecarSet
scope: Cluster => scope: Namespaced

Why is this needed:
The actual production process is divided by namespace. We have not yet considered which scenarios cannot be covered by namespace-level resources. Instead, cluster-level resource design will lead to constraints.

it is a good suggestion, however it is not possible to change sidecarset to clusterscope, instead, an extra namespace scoped sidecarset should be introduced.

I re-read the official documentation and found that the native sidecar can basically replace this enhanced resource.

sidecarset is not conflict with native sidecar; native sidecar does not support sidecar injection and independent update, sidearset can inject normal and native sidecar, and sidecarset can inplace update normal sidecars
