Allow DEFAULT in data-ciphers and report both expanded and user set option

This adds support for parsing DEFAULT in data-ciphers, the idea is that people
can modify the default without repeating the default ciphers.

In the past we have seem that people will use data-ciphers BF-CBC or
data-ciphers AES-128-CBC when getting the warning that the cipher is not
supported by the server.  This commit aims to provide a better way for
these situation as we still want people to rely on default cipher selection
from OpenVPN when possible.
