grouperinstaller might not stop tomcat correctly

If grouper installer tried to stop tomcat 8.5, sometimes it might not be started all the way... maybe wait a tad and try again if stack?

Tomcat stop with command (note you need CATALINA_HOME and JAVA_HOME set):
/tmp/grouperInstall/apache-tomcat-8.5.12/bin/shutdown.sh
