Unable to create EC2 instance with EBS block device mappings

[SuperGeno]

Description

Unable to set up/configure EBS block devices within EC2 instance template.

Expected behavior

Should be able to set up/configure EBS block device mappings within EC2 instance template.

Observed behavior

When EBS block store configuration is declared within the ec2_instance template, running a convection diff/print_template/converge fails with undefined local variable or method 'config'.

It looks like the problem is just due to using the wrong variable name (config vs. ebs) when setting up the EBS properties in aws_ec2_block_device_mapping.rb.

No issue with setting up/configuring Ephemeral storage.

Steps to Reproduce

Install version 1.0.4 of the gem and run convection print_template on a stack that includes ebs block definition within an ec2_instance template:

ec2_instance 'MyEC2Instance' do
  # some settings

  block_device do
    device_name '/dev/sdf'
    ebs do
      volume_size 30
      delete_on_termination true
    end
  end
end

@SuperGeno you can use 'convection', >= 1.1.0 in your Gemfile/gemspec for these changes.
