T6486: T6379: Rewrite generate openvpn client-configmergify/bp/circinus/pr-3747
This command helps to generate users `.ovpn` files Rewrite `generate openvpn client-config` to use Config() It needs to get the default values as `ConfigTreeQuery` is not supporting default values. Fixed "ignores configured protocol type" if TCP is used Fixed lzo, was used even if lzo not configured Fixed encryption is not parse the dict (cherry picked from commit fe50f1a9292b34e168b35453f2cfc2aee2ca4843)
