This: 1. Removes the `filestore` property from the `ModuleSystem` in favor of the `runtime.resources_fs` property. In the original code, `filestore` is equal to `DescriptorSystem.runtime.resources_fs`. It's safe to replace it with `ModuleSystem.runtime.resources_fs` because both runtimes are combined using the `CachingDescriptorSystem`. It provides the `resources_fs` property that uses the same file storage. 2. Renames `filestore` argument to `resources_fs` in the `LoncapaSystem` constructor. 3. Adds the deprecated `filestore` property to the `ModuleSystemShim` and `RuntimeShim`.
