DOCS-3129: Document license agent removal for Calico Enterprise 3.24 - #3148
Merged

Conversation
The license agent is removed in Calico Enterprise 3.24.0-3.0 and is no longer maintained. No license-agent image is published for this release or later. - Release notes: add a "Deprecated and removed features" entry, plus an "Upgrade notes" subsection pointing to the platform-specific cleanup steps. - Upgrade guides (helm, operator, openshift): document how to uninstall the agent, preferring the versioned manifest from the release being upgraded from, with a manual resource cleanup fallback. Each links to the license metrics documentation. - Redirects: point the removed license-agent metrics page at the license options page for the latest and 3.24 paths. These are non-forced 301s, so they stay dormant while 3.23 remains latest and activate once 3.24.0-3.0 ships.
