Add Status field to inventory items

[ITJamie]

NetBox version

v4.0.6

Feature type

Data model extension

Proposed functionality

add a "status" field to the inventory item model

Use case

being able to document the state of inventory items would be useful.
example states:

• active
• failed
• missing/removed (to document that an inventory item wasn't seen during last audit/check)

it would be great if this choices list could be extended like some of the status fields can be

Database changes

add a status field to the inventory item model

I think it would make sense for the default choices to match the ones for module status, but should allow for extension as well.

Couldnt the Custom Fields be leveraged for that?

[arthanson]

Module status fields are:

    STATUS_OFFLINE = 'offline'
    STATUS_ACTIVE = 'active'
    STATUS_PLANNED = 'planned'
    STATUS_STAGED = 'staged'
    STATUS_FAILED = 'failed'
    STATUS_DECOMMISSIONING = 'decommissioning'
