When adding an existing ssh key the user is required to provide a name for the key he's adding (uploading). To the newbie user it is not obvious what he shall provide as name. We should help here a provide some sensible default name.

How to reproduce:

1. ASSERT: make sure you have an account on OpenShift and in the OpenShift Explorer
2. EXEC: in the OpenShift Explorer: pick "Manage SSH Keys..." from the context-menu of your user
3. EXEC: in the upcoming dialog: hit "Add"

Result:
You get a dialog that asks you to browse and select your key and provide a name for it.

Expected:
Automatically provide some meaningful default name so that the newbie user may just pick his key and upload.
