Currently, there is a servlet for downloading the agent module zip. It'd be good to have also an endpoint for downloading the installer jar and depending on the query params, change the internal property file so that all user needs to do in order the agent is to run

java -jar agent-installer.jar

the agent installer can download the module zip from given URL so it'll use the abovementioned endpoint

There should be also a UI page with some simple form where user can overrides the default fields in the property file, like wildfly-home (where is the WF installed on her box), username, password, etc. This page should be accessible only in the experimental mode (from beginning).
