Rack Support

[joeyberkovitz]

Closes #352

New resources:

• netbox_rack
• netbox_rack_reservation
• netbox_rack_role

New data sources:

• netbox_rack_role
• netbox_racks

Adds support for referencing rack and rack location in a netbox_device resource and data source

Depends on fbreckle/go-netbox#27, tests will break until merged. Tests will also break in master if the go-netbox changes are merged without this PR (specifically commit minimal updates to API 3.4).

Added minimal support for API version 3.4 to ensure that current functionality remains the same

[joeyberkovitz]

pushed an update to fix the device rack functionality when a rack is cleared out after being set

let me know once the netbox client PR is merged and I can update the go.mod

Also note that TestAccNetboxProviderConfigure_failure started to fail for me with error context deadline exceeded instead of a DNS lookup failure. If it fails on the CI/CD server, this may need to change, but I left it as is since it's unrelated.

[joeyberkovitz]

not sure why the code is failing to build for the tests given that it seems to work fine locally with the same go.mod as on git

[joeyberkovitz]

rebased to master and fixed the issue caused by the merge, hopefully should work now

[joeyberkovitz]

Looks like tests fail on older versions of netbox which don't support the new attributes added in API 3.4. I think those attributes are primarily metadata, so I can remove them from the tests unless you have any suggestions?

[fbreckle]

Since this patch contains content that is useful for 3.3 users, I think we should for now continue supporting that version.
Then, when a new 3.3 version is out and there are on features pending on the provider, we can make the jump to release only for 3.4.
Edit: Just to point out: what you did in 498f31c was what I wanted

TIL Go now has generics 😮
