[Task]: Change AES Algorithm on AesTwoWayPasswordEncoder

[hansva]

What needs to happen?

Currently we are using following AES algorithm: AES/ECB/PKCS5Padding This mode has been deemed unsafe and needs to be upgraded to use a better algorithm.

Changing this would be a breaking change for people currently using the AES strings in their configuration so clear communication will be needed

It's perhaps better to create a new plugin AES2 or something like that. Leave deprecation warnings in the logging when using the old plugin.
