`openvpn` implementation doesn't seem right

[tym2k1]

meta-rte version (if applicable)

v0.7.5 and onward

Affected component(s) or functionality (if applicable)

OpenVPN

Brief summary

1. Misaligned references

The openvpn_%.bbappend recipe specifies that the config for the rte openvpn service should be at /data/openvpn/
while the openvpn@.service we implement checks for /storage/openvpn/rte.conf which doesn't exist.

We also use sed to replace openvpn references to /etc with /storage while README.md specifies putting the rte.conf on the /data partition.

2. The service seems broken on version 0.7.5

When working on #70 I keep getting an error:

ERROR: openvpn-2.6.10-r0 do_package: Didn't find service unit 'openvpn@rte.service', specified in SYSTEMD_SERVICE:openvpn-rte. Also looked for service unit 'openvpn@.service'.
ERROR: Logfile of failure stored in: /build/tmp/work/cortexa7t2hf-neon-rte-linux-gnueabi/openvpn/2.6.10/temp/log.do_package.39524
ERROR: Task (/build/../work/meta-openembedded/meta-networking/recipes-support/openvpn/openvpn_2.6.10.bb:do_package) failed with exit code '1'

It seems we must implement some default rte.conf and ensure that it's disabled by default

[macpijan]

Let's just drop it if it causes too much trouble. I thought I suggested elsewhere that we do not use openvpnv, so we can remove drop it, or simply keep installed in image, but drop all customizations.

[tym2k1]

Then i'll remove all customization so it uses the standard recipe from poky and ensure that the service is disabled by default. If someone needs they'll be able to add their config and start the service.

[macpijan]

Makes perfect sense to me.

@tym2k1 manual check needed - please confirm/resolve the issue.
