Document connection lifetime

[Sytten]

A few releases ago we added max_connection_lifetime (default None) and max_idle_connection_lifetime (default 5m) to the engine. Those should be documented.

Hold: We are not ready to document these features yet.

[rpbarnes]

are y'all going to document these? Is it possible to set a max_connection_lifetime? Does it default to 5m? I searched the docs and can't find anything for max_connection_lifetime.

So, what can we do to recycle connections in the meantime then?

Any updates?
