General: Refactored extract hierarchy plugin

[iLLiCiTiT]

Brief description

Refactored extract hierarchy plugin.

Description

Changed extract hierarchy plugin to not use recursions but be queue based. Updates of entities does not override full data on entity but only modified or new keys. Asset update is not skipped if new entity should not have tasks. Asset on instance is updated with new data on it even if was prefilled before. Prequery documents at once instead of one by one.

Additional information

There is still missing validation of changing parents or possible change of name of asset. That should be added in future too.

Testing notes:

Editorial publishing should create/update entities without any issues.

1. Creation of assets should work as expected
2. Updating of assets should work as expected
3. Creation of assets without tasks should not cause any weird data on asset
