EAP 7.1 cache-type attribute of security-domain element accepts invalid values

Issue

It is possible to define the following without JBoss complaining:

<subsystem xmlns="urn:jboss:domain:security:3.0">
<security-domain name="iskv21c" cache-type="InvalidValue">
[...]

Expected behavior is that JBoss complains about invalid value "InvalidValue" (e.g. throws an Exception, refuses to start,..)

According to the CLI, there are two valid options: default and infinispan
and only those two options should be accepted during validation process.
