This module provides a way to use services when preprocess entities.
It does this by adding a service pass and provider.

It is built for developers and doesn't add any special functionality
out of the box.

The module will however be able to call services out of the box for nodes and paragraphs.
But can easily be used for all entities.

You just have to call the following function:
_entity_preprocess_services_preprocess_entity

See configuration on how to use this.
