Copy the Java SDK SecretCache

[NikolayMetchev]

the Java SDK has a class called SecretCache. https://docs.aws.amazon.com/secretsmanager/latest/userguide/retrieving-secrets_cache-java-ref_SecretCache.html
Can we add that to the Kotlin SDK. Or should we use the Java version directly?

That SecretCache is a custom library handwritten for the Java SDK. https://github.com/aws/aws-secretsmanager-caching-java

We currently don't plan to implement a custom handwritten secrets caching library, but I'll leave this open as a feature request for other to provide feedback and help us prioritize the issue.
