Description of problem:

OpenVPN doesn't support <cert>, <key>, <ca> tags in config

Version-Release number of selected component (if applicable):
NetworkManager-openvpn-1.0.2-2.fc22.x86_64

How reproducible:
very

Steps to Reproduce:
1. generate openvpn config with <cert>, <key>, <ca> tags instead of separate files
2. select network, add network connection, import from file
3. choose the generated config

Actual results:
can't import openvpn config

Expected results:
i should be able to import this openvpn config as it is a valid one (openvpn /path/to/config works from cdm)

Additional info:
Here's a sample config:

$ cat openvpnconfig.conf
client
dev tun
proto tcp
remote someserver.com 1194
resolv-retry infinite
nobind
persist-key
persist-tun
<ca>
-----BEGIN CERTIFICATE-----
$CA HERE
-----END CERTIFICATE-----
</ca>
<cert>
-----BEGIN CERTIFICATE-----
$user_cert HERE
-----END CERTIFICATE-----
</cert>
<key>
-----BEGIN PRIVATE KEY-----
$user_key HERE
-----END PRIVATE KEY-----
</key>
ns-cert-type server
comp-lzo
verb 3
route-method exe
route-delay 2



Such a config works fine from cmd. I think it's reasonable to think it would work in NM.
