feat: add VM resizing for device resource core upgrade and new device status for device data source

[rling-equinix]

In Dec release, we added the "core" field to the Update Virtual Device API to allow users to resize their devices. After device is provisioned, the customer can send a PATCH request to upgrade its core number. The device will be marked as "RESOURCE_UPGRADE_IN_PROGRESS" and once the upgrade is done, the device status will be provisioned again.
More details could be found in our API documentation.

go.mod and go.sum needs to be updated after equinix/ne-go#26 (go client) is merged.
