RHDM 7.2 Installation guide for JWS missing instructions

The KIE server assembly for JWS is the same for RHDM and RHPAM. Although RHDM does not require a datasource, a web.xml in the KIE server contains org.jboss.narayana.tomcat.jta.NarayanaJtaServletContextListener, which depends on specific libraries being on Tomcat's classpath.

The following part of the RHPAM documentation should be included into the RHDM doc:

Copy the following libraries from the offline Maven repository to the JWS_HOME/tomcat/lib folder:

org.jboss.spec.javax.transaction:jboss-transaction-api_1.2_spec
org.jboss.integration:narayana-tomcat
org.jboss.narayana.jta:narayana-jta
org.jboss:jboss-transaction-spi
