Exit cell on the model of setup cell

[AdrienDart]

Description

Can we please have some sort of exit/cleanup/teardown cell that will be forced to run last?

The use case being I have some connection that is opened during the notebook execution and I want to close it after executing the whole notebook.

Is there any other way to achieve that?

Thanks!
