Expressroute bandwidth reduction doesn't de-provision and re-provision circuit as would be expected

[hawk0013]

When changing bandwidth_in_mbps to a value less than the currently provisioned amount, Terraform should deprovisioned and reprovisioned the circuit. Currently it will just try to directly change bandwidth_in_mbps and of course would fail, due to limitations described below.

https://docs.microsoft.com/en-us/azure/expressroute/expressroute-howto-circuit-portal-resource-manager
"Although you can seamlessly upgrade the bandwidth, you cannot reduce the bandwidth of an ExpressRoute circuit without disruption. Downgrading bandwidth requires you to deprovision the ExpressRoute circuit and then reprovision a new ExpressRoute circuit."

This has been released in version 2.10.0 of the provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading. As an example:

provider "azurerm" {
    version = "~> 2.10.0"
}
# ... other configuration ...
