Feature Request: Allow custom status choices

[sirance]

Hi there,

Currently field choices appear to be validated against a hard coded list. It would be great if they could instead be validated against a list obtained from the netbox api. This would then support the use of custom field choices. I believe this can be obtained via the api as documented here

An example use case for this is for the IP Range resource. We have added a DHCP status choice, so we can document our DHCP pools. However we can't add these via terraform as the status validation currently fails.

Thanks!
