Add checkpoint test for various AES decryption usages

[Zech-Hein]

Currently, there are checkpoint tests for the passwordUtils which is responsible for AES password decryption. See https://github.com/OpenLiberty/open-liberty/blob/7eb1c7bd95bd5903653bd617458d393c8ce66f83/dev/io.openliberty.checkpoint_fat/fat/src/io/openliberty/checkpoint/fat/PasswordUtilsTest.java

However, the existing tests only cover aes decryption for the authData server configuration field. See https://github.com/OpenLiberty/open-liberty/blob/7eb1c7bd95bd5903653bd617458d393c8ce66f83/dev/io.openliberty.checkpoint_fat/publish/servers/checkpointPasswordUtilities/server.xml
Example:

<authData id="defaultAuthData" user="APPUSR" password="${default.user.password}" />
<variable name="default.user.password" defaultValue="{aes}APb9ZaYzUL+JsfFD/OOBGaPM0evjmx5AnvmzbaKgffyX" />

We should test decryption in checkpoint tests for other config element like basicRegistry and keystore

Example usage of aes decryption for basicRegistry:

<user name="customUser" password="{aes}AL4f8Vek3bMHFusOdK3KleiHJRh8ghFdc5OzO8vo3UtRKprTjetDKmaG7NWRLX0qaA==" />

Example usage of aes decryption for ssl config element

<keyStore id="defaultKeyStore" password="{aes}AGhU2J3FXiBOCTxZI4hRLWwezyITmEf4BGfRc5KyAjFq" />
