Public bug reported:

Given the following code on a EL based distribution:

```
def crtfile_to_pubkey(fname):
    pipeline = ('openssl x509 -noout -pubkey < "$0" |'
                'ssh-keygen -i -m PKCS8 -f /dev/stdin')
    (out, _err) = util.subp(['sh', '-c', pipeline, fname], capture=True)
    return out.rstrip()
```

Cloud-init is unable to generate a ssh public-key from the azure PKCS8 certificate.
The version of ssh-keygen on EL distributions does not have a -m flag.
