/**
* Remote AdminCommand to validate a config Node. This command is run only on DAS.
* This command does the following:
*
* If the node does not exist it returns an error
*
* If parameters are passed to the command, such as nodehost, then it verifies
* the parameters passed to the command match what is in the config. If the
* config does not match the passed parameters then it is an error -- unless
* the config has no value.
*
* If the node exists, but does not have some of the attributes passed to
* the command, then the node is updated with the values passed to the command.
