Title: fixes #108: persist identity keys in b2d

This changes where the identity keys are stored in b2d. This persists through reboots and stop/starts.

Note: I also created a new b2d iso for testing as the current one had issues with TLS and ports.

`machine create -d virtualbox --virtualbox-boot2docker-url https://ehazlett.s3.amazonaws.com/public/boot2docker/boot2docker-machine-87e3813.iso machine-test`
