doc: placement API ref for resource classes points to os-traits

[Eric Fried]

The placement API reference documentation for POST /resource_classes [1] says:

The new class must be a custom resource class, prefixed with CUSTOM_ and distinct from the _standard_ resource classes.

...where _standard_ is a link to os-traits documentation [2]. Since we don't have os-resource-classes (yet), the linkitude should just be removed.

    Doc: Nix os-traits link from POST resource_classes

    The placement API reference documentation for POST /resource_classes [1]
    said:

    The new class must be a custom resource class, prefixed with CUSTOM_ and
    distinct from the _standard_ resource classes.

    ...where _standard_ was a link to os-traits documentation [2]. Since we
    don't have os-resource-classes (yet), this change set removes that
    linkitude.
