Manage UID/GID with puppet

Set uid and gid values for users that puppet creates so they are
consistent across all systems.  Pick some arbitrary values for them
and set them for all current users.  Remove users who haven't been
around for a while (their ssh keys should all be removed at this
point).

I do not know what puppet will do with existing users (whether it
will attempt to change their entries or not), so do not merge this
change until all existing servers have been updated.
