Set default color for device and rack roles

[jkldgoefgkljefogeg]

Environment

• Python version: python:3.7
• NetBox version: 2.8.4

Proposed Functionality

when adding a device role, color is currently a mandatory field. I propose making this field optional and auto assign an unused color if none specified

Use Case

When there are many device roles, it is difficult to pick a unique color.

The field must remain mandatory. What we can do is set a (non-configurable) default color, but NetBox will not assign colors randomly.

That works too.
Just curious what is the history with device role label/color, I suspect some don't know what this is useful for

[czarnian]

Default color sounds good. Making it configurable in UserPreferences would cease discussion about what color to use.

[jeremystretch]

@czarnian we won't make it configurable, foremost because it would lead to a nondeterministic condition when creating a role via the REST API with an unspecified color.
