Bug 818896

Description of problem:
Create an app with an upper case name: "APP". Create another one with an lower case name: "app" and you will get "Error communicating with DNS system." Create an app named "app" again and it will succeed. Since domain is case-insensitive, we won't be able to access "APP" any more.

Version-Release number of selected component (if applicable):
stage-2.0.10

How reproducible:
Always

Steps to Reproduce:
1.Create an app with an upper case name: "APP"
$ rhc app create -a APP -t php-5.3 -dp redhat
2.Create another app with a lower case name: "app"
$ rhc app create -a app -t php-5.3 -dp redhat
3.Create an app named "app" again
$ rhc app create -a app -t php-5.3 -dp redhat
  
Actual results:
2.app creation failed.

RESULT:

<----------------------------->
3.app is created successfully.

Expected results:
2. Error message should be more friendly like "app already exists" or "DNS already exists".
3. app shouldn't be created, or we won't be able to access "APP" any more.
