Prefer `*_DNS` to `*_UUID`.

test on devenv_3716, same error as Bug 974933 when threaddump a scale up gear.

steps:
1. create ruby scalable app

2. visit the app and run rhc threaddump
[root@Daphne test]# rhc threaddump ruby19
Success
The thread dump file will be available via: rhc tail ruby19 -f
/var/lib/openshift/816631724363555310403584/ruby//logs//error_log-20130828-* -o '-n 250'

3. scale up

4. visit the app and run rhc threaddump again
[root@Daphne test]# rhc threaddump ruby19
Error occured while processing event 'thread-dump':The rhc threaddump command is not supported
on scaled gear: 50d93dd60fb911e3b11c12313b0ca01b. ssh into the gear and issue
~/ruby/bin/control threaddump.
