In WFLY-9463 the jndi-name attribute in infinispan subsystem model was deprecated and in fact it is ignored when specified in CLI command, eg:
/subsystem=infinispan/cache-container=testInfinispan:add(jndi-name="java:jboss/infinispan/testInfinispan") the value is ignored and not persisted in latest Wildfly.

Therefor, it should be safe to remove this attribute also from installer (one field less to fill for user).
