Mill Init 2.0.0

Release 2.0.0 transitions the mill to use Amazon's Elastic File System EFS for task processing related disk IO.

In order to use this version you must first do several things.

1. Create a Virtual Private Cloud (VPC) or use the default VPC.
2. Enable DNS Resolution and DNS Hosting on the VPC.
3. You must create a security group with open incoming NFS port (2049) that is limited to that self-same security group.
4. Create a new file system in AWS EFS.
5. Associate the security group you created with the EFS mount targets (can be done through AWS Console > EFS )
6. Link to the VPC and select the newly created security group in your launch configs.
7. In your autoscale group, be sure to add the subnets with availability zones that match the availability zones configured in the autoscale group.
