Frank Lichtenheld b0fc10abd0 samples: Update sample configurations
- Remove compression settings. Not recommended anymore.
- Remove old cipher setting. Replaced by data-ciphers negotiation.
- Add comment how to set data-ciphers for very old clients.
- Remove/reword some old comments. e.g. no need to reference
  OpenVPN 1.x anymore.
- Mention peer-fingerprint alternative.
- comment out "tls-auth" as that is not needed for a bare-bones VPN config
  and needs additional setup.

# Sample client-side OpenVPN 2.6 config file #
# for connecting to multi-client server. #
# #
# This configuration can be used by multiple #
# clients, however each client should have #
# its own cert and key files. #
# #
# On Windows, you might want to rename this #
# file so it has a .ovpn extension #

# Specify that we are a client and that we
# will be pulling certain config file directives
# from the server.

# Use the same setting as you are using on
# the server.
# On most systems, the VPN will not function
# unless you partially or fully disable
