Add 'openssl req' option to specify extension values on command line
The idea is to be able to add extension value lines directly on the
command line instead of through the config file, for example:
openssl req -new -extension 'subjectAltName = DNS:dom.ain, DNS:oth.er' \
-extension 'certificatePolicies = 1.2.3.4'
Fixes #3311
Thank you Jacob Hoffman-Andrews for the inspiration
