Change linux resource to azure_linux_virtual_machine

[JeffGiroux]

The BIG-IP is deployed now with the azurerm_virtual_machine resource. There is a new resource that has greater flexibilty called https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs/resources/linux_virtual_machine. Please look into updating the module to support this.

Note:
The azurerm_virtual_machine resource has been superseded by the azurerm_linux_virtual_machine and azurerm_windows_virtual_machine resources. The existing azurerm_virtual_machine resource will continue to be available throughout the 2.x releases however is in a feature-frozen state to maintain compatibility - new functionality will instead be added to the azurerm_linux_virtual_machine and azurerm_windows_virtual_machine resources.
