Scene Inventory: Errors during updating/managing of containers should report nicely

[BigRoy]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior:

Things like LoadError or other errors during updating or managing of loaded containers tends to just stop the updating and have the error in the console log. This was apparent e.g. during testing ynput/ayon-maya#3 (review)

Expected Behavior:

We should make it obvious to the user that something failed, and preferably have a good clear message about "what" failed if we know about it. As such it comes down to:

• Raising clear errors from the Loader plug-ins.
• Providing a nice visual dialog on errors (similar to Load errors from Loader?)

We may want to continue updating the others and then collect the errors along the way to represent one dialog at the end of all containers that failed to update.

This also solves the issue that if you select multiple containers, update all at once but one fails midway that the others you had selected do still get updated.

Version

1.0.0

What platform you are running on?

Windows

Steps To Reproduce:

Try the reproducable steps from this PR:

1. Load a Maya reference
2. In outliner enable > Display > Ignore "Hidden in outliner"
3. In AVALON_CONTAINERS add an object into the reference container (just so that maya does not auto-delete it in next step)
4. On the loaded maya reference remove the reference (via Maya itself, not via AYON tools)
5. Container object set should still exist, but no reference node
6. Via Ayon > Manage.. try to set the version of the container - it will fail.
