Maya + Redshift: Deadline render duplicates <aov> in output render

[BigRoy]

Running version
3.14.4-nightly.1

Describe the bug

Redshift renders through Deadline with Merge AOVs (= Multilayer EXR) disabled will render with a double <aov> (RenderPass) in the filename. Like this:

Publishing will fail since the metadata will expect the AOV / RenderPass token to exist only once (and for the Beauty layer by default to not be there at all - hence why it has a single token in the screenshot)

This issue originates from the Deadline submitter taking the file prefix from the layer metadata from lib_renderproducts and assign that as the file prefix for the Deadline submission

But the Layer Metadata in lib_rendersettings collects the file prefix that matches what the renderer produces as output - and doesn't necessarily match the input setting.

Hence you get an _<aov> token forced in that:

The Deadline submitter thus should not take the prefix from the layer metadata but from the scene render settings instead.

To Reproduce
Steps to reproduce the behavior:

1. Render with Redshift from Maya without merge AOVs / multilayer through Deadline.
2. Publish of rendered images fails.

Example settings:

Expected behavior

Output from Deadline should not deviate from scene settings.
And above all, publishing must work.

Desktop (please complete the following information):

• OS: Windows
• Host: Maya 2022.3, Redshift 3.5.06

Additional context

Issue likely has been introduced with the implementation of the new deadline submitter which uses the Abstract Deadline Submitter as base.
