Description of problem:
While going through the launch instance wizard in horizon, there is an option to create a key pair. When doing this key pair creation in past versions, the resulting private pem file would automatically download. This does not happen in RHOSP 13.
Instead the user is presented with the private key and an option to copy to the clipboard. However, there is no option to just download the pem file.
This means the user must copy the key pair and paste into a file somewhere, then get the public key that was generated.
The process when going through the key pairs page directly still downloads the pem file.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Go through instance launch wizard
2. On the Key Pairs dialog, click create key pair
3. Give the key pair a name and click create
Private key is displayed and there is a button to copy to clipboard, but no download option.
The pem file should automatically download as it has in the past, or there should be an option to download it.
That change is intentional, and it was introduced in order to fix a security problem.
