Chef::Knife::SslFetch#normalize_cn

Convert the CN of a certificate into something that will work well as a
filename. To do so, all `*` characters are converted to the string
"wildcard" and then all characters other than alphanumeric and hypen
characters are converted to underscores.
NOTE: There is some confustion about what the CN will contain when
using internationalized domain names. RFC 6125 mandates that the ascii
representation be used, but it is not clear whether this is followed in
practice.
