Update r/(linux|windows)_virtual_machine_scale_set - Add health_probe_id back to Update

[ArcturusZhang]

Since the PR has already add support for passing a health probe in update request of vmss, we could re-enable this in the update method to prevent the errors from the service when upgrade_policy is set to Automatic or Rolling.

Currently, if the upgrade_policy is set to Rolling or Automatic, when updating the VMSS in place, the service will complain about missing a health probe or health extension when updating:

{
  "error": {
    "code": "BadRequest",
    "message": "Rolling Upgrade mode is not supported for this Virtual Machine Scale Set because a health probe or health extension was not provided."
  }
}

hey @ArcturusZhang

Thanks for this PR - apologies for the delayed review here!

Taking a look through this looks good to me - however to be able to run the acceptance tests in situ this is going to need rebasing on top of master; as such I hope you don't mind but I'm going to push a rebase so that we can run the full test suite here 👍

Thanks!

hi @ArcturusZhang

After running the tests it appears there's some more (conditional) logic required to be able to enable this functionality than just setting the property unfortunately:

For the moment we're going to ship the Beta of the azurerm_linux_virtual_machine_scale_set and azurerm_windows_virtual_machine_scale_set resources without this functionality (there's a known issue in the documentation for this beta resource) - but we'll take another look & fix this up once that's out.

Thanks!

Thanks a lot. But currently updating vmss with upgrade_policy of Rolling or Automatic will throw errors, is there any work around about this?

LGTM 👍

Ignoring some expected & transitory test failures (due to issues in Azure) the tests are fine:
