* site cache when run plugin does not work very well
- using cache from plugin when getNodesAttribs/getNodeAttribs (pass it into DB process from plugin process)
- Site cache is a whole hash, so to use cache when by the hash is there, instead of the specified key is there.
It is because that there might be no key defined in site table.
* with XCATBYPASS, to populate site hash before scan_plugins. Then only 1 query for site table to do whole things.
* cache site when init plugins on service nodes
* missing to comment the old codes query from xCAT DB process
