PR E — "Trace this core" button injected via PluginTemplateExtension
onto dcim.Interface / dcim.FrontPort detail pages, and embedded directly
in the netbox-osp Strand detail template.

Expects in context:
    - trace_url : the absolute path to navigate to. The view at that
                  URL resolves the underlying Strand and renders the
                  full tracer page.
