Currently xcat rest service is running with apache user who do
not have the privilege to manage some local resource like credential
files needed by xcat web ui to get the conserver access.
This patch add scripts in xcatconfig to generate credential files
for conserver user. This patch also add a work around framework for
xcat restapi to provide the interface to get or set the system resource
so that restapi with apache privilege can retrieve the credential files.
