Some concepts included:
* the replace.properties location used by maven is parameterized to allow
for a build that does not modify the currently git tracked files
* package naming is updated along the lines of what was discussed on the
-dev mailing list and between committers at the Build a Cloud Day in Belgi
* package version pattern is updated (since we redo all package names,
we might as well drop the epoch)
Modify the spec file to package the agent files and the scripts
Some changes to the poms to put the java dependencies in the right place.
Move the agent script to the dedicated os dir in packaging.
