What's Changed

While this release had a major focus on stability, we managed to optimize the startup sequence and it should make your tests even faster!

Here is what it takes to have a Redis up and running with Testcontainers, end-to-end from the test's start to an instance ready to be connected:
Before (1.17.1): 2.4s
Before (1.17.2): 1.7s 🚀

And here is just the "initialize Testcontainers" measurements:

Before (1.17.1): 1102ms
Before (1.17.2): 928ms

How we did it? We noticed that we can cache a couple of Docker responses, plus also removed now obsolete (yet expensive!) disk space check.
