Currently I'm facing an issue with stale DB connections. It's probably
related to my setup. Having `connection_closed` signal would simplify my
debugging process.
Since 2009, there's `connection_created` signal.

I'd like to create a `connection_closed` signal and connect it here
https://github.com/django/django/blob/6f38697f90a14f1450a71c1e40aea0f5df7dca86/django/db/backends/base/base.py#L314
This way the connection can be accessed right before closing it.
I'd be happy to implement it. Let me know what you think.
I'm also open to `pre_connection_closed` and `post_connection_closed`.
Even though not many people will ever use it, I can imagine wanting both
in different cases.
