[JBQA-8003] + [JBQA-8722]: Test development

https://issues.jboss.org/browse/JBQA-8003
https://issues.jboss.org/browse/JBQA-8722

These test were already merged, but they have been reverted because one test was unstable: https://github.com/wildfly/wildfly/commit/e8ba6cb65428cf67ed6bc06c5e0ab0f5ec0ba794

 Now it should be fixed + I added JBQA-8722: test for vault encrypted passwords in jboss-cli.xml
