Render review and thumbnail fail due to missing OCIO config

Is there an existing issue for this?

• I have searched the existing issues and added correct labels.

Description

Current Behavior

With path to OCIO config set in core settings: ayon+settings://core/imageio/ocio_config_profiles for Blender host,
Using Cycles renderer with compositing enabled fails to make review and thumbnail on farm.

The OIIOtool expects valid path to OCIO.

Steps To Reproduce:

1. Configure OIIOtool to convert the exr to png sequence
2. Publish exr render from Blender 4.2 to Deadline
3. No review or thumbnail is created

Additional context:

Version

Server 1.42, ayon_core 1.06, ayon_blender 0.2.5

What platform were you running when you found the bug?

Windows

You can also provide any additional information relevant to the issue.

This change can be a quick fix:

• It uses OCIO path from envinronment (might be an issue for multi-platform farms)
• The hardcoded Display and View values are swapped and use more typical OCIO 1.0 names

A potential fix for this is in this PR here: #67

See the code here

Because there I did end up collecting the colorspace from the configuration set up in the Blender file itself.

The display + view from Blender is cool, thank you!

Just wondering, maybe we should set the colorspace by the Node override, and not display & view?

Imho it would be great to have something like Maya workfile settings, where we can setup default rendering space, together with display and view:
