[lack]

- What I did

Updated the kubensmnt dependency to v1.3.0 to incorporate the upstream fix for OCPBUGS-83562

Deploy, enable the 'kubens.service', and ensure that /run/netns/ is a mountpoint both in the default system namespace:

mountpoint /run/netns/

and the kubens namespace

kubensenter mountpoint /run/netns/

- Description for the changelog

Updated kubens.service to eliminate a race condition between CRI-O and external network tools running ip netns add

Walkthrough

This PR updates the kubensmnt module dependency from v1.2.0 to v1.3.0 and adds systemd unit initialization to ensure the /run/netns shared mount point exists, preventing setns errors and mount shadowing issues that occur with CRI-O-created mounts.

Changes

Netns shared mount point initialization

Layer / File(s)	Summary
kubensmnt module upgrade and systemd ExecStartPost initialization go.mod, templates/common/_base/units/kubens.service.yaml	The kubensmnt dependency is bumped to v1.3.0; an ExecStartPost step is added to kubens.service.yaml that initializes /run/netns as a shared mount point by creating and immediately deleting a temporary netns (kubensmnt), with a fallback mountpoint check to ensure the initialization succeeds.

In `@go.mod`:
- Line 16: The go.mod currently pins a non-existent module version
"github.com/containers/kubensmnt v1.3.0"; fix this by either removing that
require entry or replacing v1.3.0 with the correct release tag from the upstream
repo. Locate the "github.com/containers/kubensmnt" require line, verify the
correct tag on the upstream (or decide the dependency is unused), then run the
appropriate go tooling to apply the change (e.g., use `go get
github.com/containers/kubensmnt@<correct-tag>` or delete the require and run `go
mod tidy`) so the module version in go.mod is valid.
