OpenSSH-generated private keys do not work in App CR

[bcdurden]

When creating an App object using a ssh-git source and ssh private key, if the key was generated using openssh (default on MacOS as of this date) then it will fail complaining of key formatting.

What are the headers of your private key? Like -----BEGIN OPENSSH PRIVATE KEY----- or what?

A repro of this would be helpful.

Ah, I see the thread on Slack mentions that it is -----BEGIN OPENSSH PRIVATE KEY----- and that appears to be the problem

Yes, sorry I should have been more specific. That header is specifically what triggers it I believe. When I switched to something with -----BEGIN RSA PRIVATE KEY----- it worked
