upgrade to tomcat 7.0.56
upgraded tomcat connector
opal: upgrade at version 2.6

I haven't officially tagged yet the 2.6 but this package was create at
commit 9dd706bbcc67b8ab11ba5d6c35e5d6801ab0cd0e of opaltoolkit
Most likely I will cut the 2.6 from there...
fix tomcat connector

apache modules are not stored in /usr/lib64/httpd/modules and not
anymore in /etc/httpd/modules

This patch fixes this problem
remove creation of user ssh keys

Since now rocks uses host based authentication we don't need
anymore to set up user ssh keys
fix opal installation path

opal should installed in /opt/tomcat
node.xml: use new deployment
node.xml: fix bug with opal.properties configuration
node.xml: open http on opal-server appliances
add here a helper script to compile the entire software stack

this script can be use to compile all the NBCR roll necessary for
deploying the NBCR web service gateway
change deploy diretory to /opt/opal/deployed

We can't use /opt/tomcat/deployed because it is a symbolic link and
if we create a package with a file in that folder it will remove the
symbolic link
