Cannot mass edit device types to 0U

[jakubkrysl]

Environment

• Python version: 3.6.15
• Nautobot version: 1.2.4

0U is valid height when creating or editing a device type, but mass editing does not allow this.

Steps to Reproduce

1. Create 2 device types
2. Mass edit them to set U height to 0U

Expected Behavior

Set to 0U

Observed Behavior

Please select a value that is no less than 1.

Confirmed. Thanks for reporting this @Thetacz.

This requires two tests which both set the u_height to 0:

• A test which expects an error on submission of the bulk edit form because of rack position validation
• A test which should validate a form submission of the bulk edit form
