Publish component builder LOP usd while maintaining hierarchical structure

[BigRoy]

Changelog Description

Implements a prototype creator that can publish the output USD of a Component Builder LOPs network.

Additional review information

Example graph:

Publisher:

The published asset is contained within a single publish with all its relative paths and localized files:

Note that this screenshot does not contain the textures - but that's only because I didn't have them on my disk in this case. That's then logged forgivingly as a warning during publish. For example:

Selecting the Creator in the publisher UI and pressing the question mark on the top right of the publisher UI will try and guide you about what it does and how to use it.

Testing notes:

1. Create component builder network in LOPs
2. Select a component output node in the graph
3. Create the component builder LOPs instance
4. (Optional) Disable the USD contribution workflow on the instance. (Since the component builder basically 'defines' the full USD asset it makes little sense to contribute it as part of a parent asset using a contribution workflow.)
5. Publish

I got an error on integration step because it expected a thumbnail.
The fix to click Generate Thumbnail

using the following publish template :

1. in ayon+anatomy://RnD/templates/publish

   {
     "name": "HoudiniComponentBuilder",
     "directory": "{root[work]}/{project[name]}/{hierarchy}/{folder[name]}/publish/{product[type]}/{product[name]}/{@version}",
     "file": "{originalBasename}.{ext}"
   }

2. in ayon+settings://core/tools/publish/template_name_profiles
   

allows me to replicate have the same output with the same names in the publish folder.
but keep in mind this publish template will also be applied to all USD products!

I've just broken the contribution workflow. it doesn't respect the publish template.

I tried publishing the output of component builder as an assembly variant in usd contribution.
I may be missing a step.
Anyways, do you think it's a good thing/valuable to publish the component builder a an assembly product in a usdAsset?

Side question: What tasks types are most suitable for component builders? since component builders include look and model products.

I'd say component builder makes little sense with the contribution workflow - yet at the same time, there may be an edge case where one may want to do that and instead have it be the full usd asset itself.

Side question: What tasks types are most suitable for component builders? since component builders include look and model products.

Generic task type maybe. But yes, there isn't a clear 'default' task type in AYON that is the combination of those two.
