nomad/e2e/migrations

End to end tests for migrating data in sticky volumes

These tests run in a docker container to ensure proper setup/teardown.

To create the testing image: ./docker-init.sh

To run tests: ./docker-run.sh

TODO:

1. Specify how many servers/clients in the test
2. Have a callback to specify the client options
3. Run servers/clients in the docker container, return IP addresses for each instance, but have the test run on the host.
4. There should be a 1:1 mapping from container to agent, rather than running the entire cluster in a container.
