feature suggestion: add a callback for expired entries

[lamemind]

Hello,

At this precise moment, I'd really love a callback called just before (or right after) an entry expires.

Thanks

There is timeout callback, undocumented.

It runs after the key is deleted without sending the value into it. One of the 2 should be available:

• (preferably) sending both the key and the value to the callback
• running delete after callback so that the value could be accessed from the cache

Thoughts @ptarjan?

I like it happening after the delete since the notion of a callback is to tell you once it is done. Is be open to adding the value if you send a PR (and add it to the docs :))
