Marc Abramowitz 5b783e0bc6 Error if private_key_file is group/world readable
Currently, if you have this, ansible fails with a generic error and
suggests running again with `-vvvv`. This isn't bad but pinpointing the
specific problem immediately is even more user-friendly.

```
$ ls -l devops.pem
-rw-r--r--+ 1 marca  staff  1679 Jul  2 11:25 devops.pem

$ ansible -m ping --private-key=devops.pem mt3-pyweb01
mt3-pyweb01 | FAILED => private_key_file (devops.pem) is group-readable or world-readable and thus insecure - you will probably get an SSH failure
```
