Move metadata daemon to its own directory

Currently, the metadata daemon is mainly a web server.  However, a new
configuration server will be introduced along with other metadata
related modules.  Therefore, this patch moves the current metadata
daemon web server to its own directory.  This module is also renamed
from 'Server' to 'WebServer'.
