Support KMS asymmetric keys

Hello,

I am unable to figure out few things while using kms. I have the following use case:

1. GenerateDataKeyPairWithoutPlainText - CLI
2. Store the above generated keys in the AWS secret manager - Console
3. Fetch the public key and give it to the client - Java
4. Client encrypts data and send it to us.- Java
5. We fetch the private key from the secret manager and decrypt data sent to us by client. - Java

I have executed the first three steps and need a Java Example for the last two. Thanks!

Start by reviewing the GenerateDataKeyPairWithoutPlainText workflow described in the issue and the Java integration point for the final encryption and decryption steps. A useful result would document how the client encrypts with the public key and how the service retrieves the private key from AWS Secrets Manager to decrypt the data.
