Closes #11670: Add ability to optionally import DeviceType and ModuleType weight

[dhenschen]

Fixes: #11670

Summary

This Pull Request adds the ability to import weight data via CSV, YAML, or JSON for Module Types and Device Types. Additionally, this PR adds the weight and weight_unit fields to the YAML export of Device Types and Module Types.

Background

Prior to this PR, the ModuleType and DeviceType modules already contained weight and weight unit fields. However, there was no ability to import this data. This PR adds the necessary functionality.

Changes

To maintain consistency, the import design of the DeviceType weight follows the same pattern used for importing weight and weight units in DCIM Racks.

The PR description includes examples of YAML imports for Racks, Device Types, and Module Types, as well as YAML exports for Device Types and Module Types. These examples illustrate demonstrate how these new import and export changes look.

Benefits

This feature improves the usability of NetBox by allowing users to import weight data for Module Types and Device Types, as requested in #11670. It also makes it easier to manage and maintain this data, as it can be imported/exported along with other relevant information.

Examples

Rack Import Example (YAML)

This is a YAML example of importing a Rack in NetBox. The below YAML worked in NetBox prior to this Pull Request.

site: DM-Albany
name: blahabc
status: active
width: 19
u_height: 42
weight: 10
weight_unit: kg

Device Type Import Example (YAML)

This is a YAML example of importing a Device Type in NetBox.

manufacturer: Juniper
model: Switch
slug: switch
u_height: 1
weight: 10
weight_unit: kg

Module Type Import Example (YAML)

This is a YAML example of importing a Module Type in NetBox.

manufacturer: Juniper
model: TEST-1001
weight: 10
weight_unit: lb

YAML Export

Attached below are example exports with the new weight and weight_unit fields included:

• netbox_device_types_yaml.txt
• netbox_module_types_yaml.txt

Thanks for such a thorough PR @dhenschen! I've merged your new tests into the existing test_import_objects() tests just to reduce redundancy.
