kube_lease_renew_time needs namespace label

[mrueg]

What happened:
The metric kube_lease_renew_time{lease="foo"} is describing a namespaced object but not exposing the namespace. This can lead to metric collisions if there are two leases in different namespaces.

What you expected to happen:

Expose the namespace label for kube_lease_renew_time in internal/store/lease.go

How to reproduce it (as minimally and precisely as possible):

Create two leases with the same name in different namespaces.

Anything else we need to know?:

Environment:

• kube-state-metrics version: 2.8.2
• Kubernetes version (use kubectl version): 1.23
• Cloud provider or hardware configuration: Kind
• Other info: None
