domain.sh -domain-config parameter cannot accept an absolute path

The -domain-config paramter of domain.sh command can only accept a filename, not an absolute or relative path. This means that you have to copy your alternate config file into JBOSS_HOME/domain/configuration/ before using it. This behavior is inconsistent with the -server-config option of standalone.sh, which can take either an absolute path, relative path, or if just given a filename, assumes the file is in standalone/configuration/.
