[Hawkular-dev] Agent installer

So far we have an agent installer download page as an experimental feature. I would be in favor of: - moving the form to the application server list - the whole form should be rendered when the list is empty to add a first server - When the server list is not empty, there should be a link to a popup - we shouldn't force a wildfly home location, I would simplify to just username and password as optional parameters. WDYT ? PS: I see 2 bugs at the moment: - It downloads hawkular-wildfly-agent-wf-extension.zip instead of the agent installer jar - the instruction for command line doesn't include the right version, it says: $ java -jar hawkular-wildfly-agent-installer-0.13.1.Final.jar while the cirrect version is 0.15.1 I think
