Allow cryptography at the System

[Otávio Santana]

The issues have the goals to:

• Make the Settings an immutable instance
• Allows cryptography at Settings

Also, make some cryptography available by default:

• plaintext, no password
• 3DES
• DES
• Allows an extensible mechanism with SPI.

Try to align with "password aliasing" in Jakarta Security, if that is still relevant to Jakarta Security (@arjantijms , any idea, if that's still relevant in Jakarta EE or has the idea been abandoned?)

Nice, I'm waiting for feedback.
I create a draft code about it:
