Use HTMX to render device status/config/LLDP views

[jeremystretch]

Proposed Changes

There are three subviews available under the device view which employ NAPALM to poll a live device:

• Status
• LLDP neighbors
• Configuration

These views leverage the /napalm/ endpoint under the REST API endpoint for devices to fetch this live data. Javascript handles the application of the received data to the DOM for presentation to the user.

This issue proposes two major changes:

• Relocate the NAPALM logic outside of the REST API view
• Update the UI views to call NAPALM directly, rather than employing REST API calls from the client

Justification

Processing the returned NAPALM data within the UI view affords us considerably more flexibility over what to do with the data, and greatly simplifies client side requirements. By moving this logic under the UI view, we obviate the need for the three standalone Javascript modules (status.js, lldp.js, and config.js) that exist today.

Additionally, relocating the NAPALM connection logic outside of the REST API view should make for cleaner code, however that isn't dependent on this overall change.

Closing this out, to be revisited once NetBox's NAPALM proxy functionality has been moved to a plugin per #10520.
