shell provisioner fails when using inline code

[nielslaukens]

The shell-provisioner fails to work when using inline-code:

        vm_config.vm.provision :shell do |command|
            command.sudo = true
            command.inline = <<-EOS
                true
            EOS
        end

with the following error

Something blew up Mccloud. Time for McGuyver:

Presumably, the problem is somewhere here:

• https://github.com/jedi4ever/mccloud/blob/master/lib/mccloud/provisioner/shell.rb#L25 a new StringIO is created with the contents
• https://github.com/jedi4ever/mccloud/blob/master/lib/mccloud/provider/aws/vm/scp.rb#L10 checks to see if "the file" exists...

It actually won't even work with a file either, unless you forcefully set command.inline = nil
