ARTEMIS-1058 Jars in web tmp dir locked on Windows
The embedded jetty web server's WebAppClassloader holds up
webapp's jar files and does not release them after close.
For that reason the web app's temp dir cannot be cleaned up
on Windows. (Other platforms like Linux doesn't prevent a
force delete of files even they are not released).
As long as this behavior exists we need to have a workaround
to let the tmp dir be cleaned up.
It is possible that we use a 'customized' classloader to replace
jetty's WebAppClassloader, in which we manually iterate every
JarFile resources and close them.
