Update related asset when checkout acceptance created via factory

[marcusmoore]

I noticed that creating pending checkout acceptances via the factory wasn't populating the Unaccepted Assets report page. This is because the assigned_to and assigned_type on assets are set in the CheckoutableListener when the full request is actually made.

This PR updates the factory to update the checked out asset. There is probably additional cases that should have similar behavior but this is focused on this specific case.

PR Summary

• Addition of Feature to Control Checkout Acceptance
  The code now includes an import statement for a new component called CheckoutAcceptance. This is a model or a template of sorts used in managing the checkout process.

• New Functionality for Checkout Model Updates
  A new method named configure has been introduced. Its job is to keep an eye on the creation event of the checkout model. Basically, it initiates an action just after a checkout model is created. This action is to update attributes such as assigned_to and assigned_type, based on certain conditions. This can provide better management and control of individual checkouts.
