Infinispan remote-store requires remote-servers but not marked as required in mgmt model

Affect version is actually 8.0.0.Alpha1-SNAPSHOT (before 8.0.0.Alpha1, we don't have such selection).

Command remote-store=REMOTE_STORE:add fails with this exception:

}

In $JBOSS_HOME/docs/schema/jboss-as-infinispan_1_3.xsd, it looks like the remote-server is required as it's defined as minOccurs="1":

<xs:element name="remote-server" type="tns:remote-server" minOccurs="1" maxOccurs="unbounded"/>
