Is your feature request related to a problem? Please describe.

When generating client file with for a user, it is generated in home directory of the user. That's a good idea, but file permissions doesn't match the generated user, it's owned by root and user can't edit or delete the file on it's own.

Describe the solution you'd like
When generating a client file for a user, it should set security flags according to the related user, for him to be the owner and the file can't be read by other users.

chmod go-rw $CLIENT.ovpn
chown $CLIENT $CLIENT.ovpn
