Get rid of "slaves" file and do not run "start-all" and "stop-all"

Registered by Nadya Privalova

Now we cannot start datanode or tasktracker on separate machine if namenode and jobtracker run on one machine because "slaves" cannot be populated correctly. Only node with both processes (dn+tt) may be run. But if we remove "slaves" file we will not be able to use start/stop-all.sh, start/stop-dfs.sh, start/stop-mapred.sh. So we need to use hadoop-daemon scripts.
