Java - Support AES key from ICSF for encryption

See this idea on ideas.ibm.com

We aim for an encryption with an AES key stored in CKDS dataset, hence protected with ICSF.

The targeted flow would be as follows:

1. Create an AES key in CKDS
2. Create a Java application that can read the key and perform encryption and decryption
3. Application would be executed for example from WAS_HOME/lib/ext


One would achieve that the security.xml is encrypted/decrypted with a key, without having to store this key in a file (which could then also be misused to decrypt the security.xml again if one gains access to this file, for example with UID=0)
