inconsistent naming of column PM_HIVE_PARAMS.domain_id

The column PM_HIVE_PARAMS.domain_id is not the same as the column PM_HIVE_DATA.domain_id ...
It should be PM_HIVE_PARAMS.domain_name, so that it links to PM_HIVE_DATA.domain_name.

This bug creates a problem when using global parameters in the class ServiceHandler.java, where domainId is referenced to the DomainName.
(Or another solution is to change the reference of domainId to the real domain_id instead of the domain_name...)

{code}
public String execute() throws I2B2Exception{
   ...
   while (it.hasNext()) {
      ...
      domainId = cType.getDomainName();
   }
   ...
   try {
      ...
      //Get any remaining params from the environment
for( it=pmDb.getEnvironmentData(domainId).iterator();it.hasNext();){
HiveParamData hivedata =(HiveParamData)it.next();
params.put(hivedata.getName(), hivedata.getValue());
}
      ...
   }
   ...
}
