Possibility to separate the subdirectories under server-root

As an enterprise administratator I want to separate the different locations for a Data Grid server configuration `server/conf` `server/data` `server/lib` and `server/log` instead of keeping all as a subdirectory of `server-root`.

For administration purpose it should be possible to set different locations for server/conf server/data server/lib and server/log instead of keeping all together with server-root setting.
Additionally the lib directory should be scanned recursively, resolving symlinks and supporting bare files (e.g. property files) as well as Jar files. It should also be possible to specify multiple lib directories.
