fix: handle netbox migration to disk set in MB

[sjurtf]

Update to handle NetBox 4.1.0 and above.

NetBox 4.1.0 introduced multiple breaking changes.
https://github.com/netbox-community/netbox/releases/tag/v4.1.0

Disk Size

Size was changed from GB to MB.
A migration when NetBox is started is updating the stored disk value by multiplying with 1000.

This proposed change ensures that the provider is backwards compatible in terms of HCL but still can support NetBox 4.1.0 and above.

Option number two is to rename disk_size_gb to disk_size_mb and break existing HCL.
If that is preferred let me know.

VLAN Group

The min_vid and max_vid fields on the VLAN group model have been replaced with vid_ranges, an array of starting and ending VLAN ID pairs.

I've removed the depercated implementation. VLAN Group support is pending changes in the API client.

Users Password

Password must now have at least one numeral.

Rack type

A new model has been introduced to model Rack Types.
I've removed the old references to type. The new Rack Model support support is pending changes in the API client.

@fbreckle Hi

Unfortunately, the last remaining resource requires changes in the API client in order to complete. Are you planning on patching the client?

[fbreckle]

Yes, I will update the client. I'm currenlty releasing a last version for 4.0.x with 4.0.11 support.

Then I'll get to the necessary client changes later today or tomorrow. Sorry for the delay!

As for the disk size change: I think we should change the attribute name to size_mb and include a migration for the attribute. I have actually never implemented a schema migration myelf, but a similar thing was implemented in https://github.com/e-breuninger/terraform-provider-netbox/blob/master/netbox/resource_netbox_virtual_machine_migrate_v0.go

[fbreckle]

Sigh.

Am I mistaken or is this one of these situations where the netbox devs did not properly update the openapi spec?

I have this in the openapi spec of netbox 4.1.3:

            "VLANGroupRequest": {
                "type": "object",
                "description": "Adds support for custom fields and tags.",
                "properties": {
                    "name": {
                        "type": "string",
                        "minLength": 1,
                        "maxLength": 100
                    },
                    "slug": {
                        "type": "string",
                        "minLength": 1,
                        "maxLength": 100,
                        "pattern": "^[-a-zA-Z0-9_]+$"
                    },
                    "scope_type": {
                        "type": "string",
                        "nullable": true
                    },
                    "scope_id": {
                        "type": "integer",
                        "nullable": true
                    },
                    "description": {
                        "type": "string",
                        "maxLength": 200
                    },
                    "tags": {
                        "type": "array",
                        "items": {
                            "$ref": "#/components/schemas/NestedTagRequest"
                        }
                    },
                    "custom_fields": {
                        "type": "object",
                        "additionalProperties": {}
                    }
                },
                "required": [
                    "name",
                    "slug"
                ]
            },

and I see this in the debug console when changing the new "vlan ids" field:

Content-Disposition: form-data; name="vid_ranges"

1-43

... but a vid_ranges field is nowhere to be found in the api spec. Not in 4.1.0, either. I guess I have to fiddle around and see what type it is myself. Just venting...
