Users should be addable through build system

[jamoore]

Take the SQL from
​Getting Started tiki page for creating a user and create an ant target. "del-user" would most likely also be appropriate. A long-term strategy should also be considered.

r585 added simple initial version.

r769 updates the existing functionality for passwords (#181). This needs to be extended to allow the user to enter a password. (Though difficult because of Java standard-in issues:

r1011 reimplements <adduser/> under /client and also adds <addgroup/> as well. Rather than talking directly to the database, these now use the client ServiceFactory and therefore undergo AAA (authentication, authorization, auditing), etc.

However, there was one twist. There are very nasty groovy classloader issues in making this happen. Therefore I've filed #407 to slowly port all of these to Java. Currently, log4j issues crazy errors when running adduser and addgroup. We'll have to see what we can do to get rid of them. #407 is probably the easiest solution:

public class AddUser {
  public static void main(String[] args) {
    Experimenter e = new Experimenter();
    e.setOmeName( args[0] );
    // etc.
  }
}
