Show device location in breadcrumbs

[llamafilm]

NetBox version

v3.7.0

Feature type

Change to existing functionality

Proposed functionality

When viewing a device, the breadcrumbs at the top of the page currently show the site and parent device. I'd like to also include the location here. Mockup image:

Use case

My devices are primarily organized using the hierarchy Site > Location > Device. This would save a lot of time when editing a device, to be able to quickly jump to a list of other devices in the same location. (By the way, location means room name in my system).

Database changes

none

External dependencies

At first glance, it seems like all that is required is adding these lines in netbox/templates/dcim/device/base.html

  {% if object.location %}
    <li class="breadcrumb-item"><a href="{% url 'dcim:device_list' %}?site_id={{ object.site.pk }}&location_id={{ object.location.pk }}">{{ object.location }}</a></li>
  {% endif %}

As Locations can be nested, I would assume that the full hierarchy would be desirable, so the code would be a little more complicated. It looks like it's already being done on MPTT views themselves, like Location, Region, and Site Group, so it would probably make sense to make a template tag like the existing nested_tree one to handle this use case.
