Add commands to print openssl path and openssl version

[ricklambrechts]

Add laravel command that executes the following commands and shows the output in the console.
This will help while debugging.

which openssl
openssl version
openssl help

Show warning message when openssl help is missing cms support. When user is using signature logic and you want to know openssl cms is supported.

To be honest, i think this should be inside the readme instead of a command.
