Pluggable observability?

[jdunck]

At current work, we use datadog, not prometheus. At previous work, we used an internal metrics tool.

Since the _instrumentation needs are pretty modest, how would you feel about defining an "observation sink" protocol and having a way for stamina to be configured with a dynamic callable or module to receive the observable event?

I see the implementation already uses an INSTRUMENTS list, so I think this might just mean stabilizing the interface and documenting how to add to INSTRUMENTS?

If we can agree on a design target I'm happy to implement.

I was wondering how long it'll take for someone to ask. :)

I just wanted to keep the next "big" release small. It would be useful if you could provide me with metadata you definitely want to receive, in case I might miss it. There is already the definition of RetryHook in https://github.com/hynek/stamina/blob/main/src/stamina/typing.py but at this point we still can change it.
