Description
Problem
I run tests that require a mysql. While I'm iterating on my tests, I'd like to leverage reuse to only pay that boot price on the first test, and then subsequent tests can reuse the same mysql (which is close to a 6x improvement in speed).
However, I also want the reaper to clean up this container once I'm done with my testing "session", so I don't have a mysql running that I forgot to manually clean up.
I'm imagining a config like reuse: true, reuseTimeout: 5m. Which makes it so as long as I run a test within 5m of the last test, the reaper leaves the mysql container alone, but once 5m elapses without triggering a test, the reaper cleans everything up.
I thought this might be possible today with a combination of reuse: true and TESTCONTAINERS_RYUK_RECONNECTION_TIMEOUT=5m, but that still cleans up my mysql after 5m from the first test (and also spawns a new reaper for every run, which quickly pile up):

Solution
Add a rolling reaper cleanup window
Benefit
Users can reuse containers, but not have to worry about manually cleaning them up
Alternatives
Manually delete reusable containers
