Setting the VersioningStrategy on ProjectResource is obsolete, can't figure out what the alternative is

[Pvlerick]

Standard way used to be simple:

project.Instance.VersioningStrategy = new VersioningStrategyResource { DonorPackage = new DeploymentActionPackageResource(step.Id) };

This has been made obsolete: https://github.com/OctopusDeploy/OctopusClients/blob/master/source/Octopus.Server.Client/Model/ProjectResource.cs#L105

The recommended alternative is to use DeploymentSettingsResource on the "deploymentsettings API."; I can't figure out what that means.

There is no documentation on this nowhere; looking around I found two routes which are both dead-ends:

var deploymentSettings = await client.Repository.DeploymentSettings.Get(project.Instance);
deploymentSettings.VersioningStrategy = new VersioningStrategyResource { DonorPackage = new DeploymentActionPackageResource(step.Id) };

 var deploymentSerttings = new DeploymentSettingsResource
  {
      SpaceId = project.Instance.SpaceId,
      ProjectId = project.Instance.Id,
      VersioningStrategy = new VersioningStrategyResource { DonorPackage = new DeploymentActionPackageResource(step.Id) }
  };

  await client.Repository.DeploymentSettings.Modify(project.Instance, deploymentSerttings);

Both will throw a similar exception:

Unhandled exception. System.AggregateException: One or more errors occurred. (The document does not define a link for 'Self')
 ---> System.Exception: The document does not define a link for 'Self'
   at Octopus.Client.Model.Resource.Link(String name)

For the moment, it seems the only way to deal with this is to ignore the warning.
