create an image zip for Tomcat for fabric8/tomcat-8.0

[davsclaus]

It should be similar to what the tomcat docker image does

Got a basic vanilla tomcat 8 up and running. Adjusting it to configure http/https port is to be done.

We need to be able to configure the HTTP/HTTPS port Tomcat should use

[14:15:38]  <+jstrachan>     I remember searching stackoverflow a while back and I think tomcat supports ${foo.bar} type stuff so we could have a custom server.xml with env vars inside I *think*
[14:15:51]  <+jstrachan>     if not we'll have to have a script to do it at install/start time
[14:16:00]  <davsclaus>  ah

[14:19:43]  <+jstrachan>     it definitely supports system properties http://java-monitor.com/forum/showthread.php?t=838 not sure if env vars work too
[14:19:46]  <+jstrachan>     am hoping they do ;)
[14:20:24]  <+jstrachan>     The Tomcat configuration files support Apache Ant style variable substitution. A system property with the name propname may be used in a configuration file using the syntax ${propname}. All system properties are available including those set using the -D syntax, those automatically made available by the JVM and those configured in the $CATALINA_BASE/conf/catalina.properties file.
[14:20:39]  <+jstrachan>     wonder if we can write env vars into the properties file?
[14:22:38]  <+jstrachan>     I guess we could expose the common env vars as JAVA_OPTS or something
[14:23:01]  <+jstrachan>     JAVA_OPTS=-Dhttp.port=$HTTP_PORT -Ddebug.port=$DEBUG_PORT ...
[14:23:11]  <+jstrachan>     then use ${http.port} in the server.xml
[14:23:22]  <+jstrachan>     it'd be easier if we could just refer direct to env vars though ;)

Oh looks like Tomcat also need a port for shutdown command

<Server port="8005" shutdown="SHUTDOWN">

its working fine now for version 2.0.2; we just need to rename it to tomcat-8.0 to match the docker image - will do that after the 2.0.1 release of the quickstarts...
