Daniel Dao ca114f7812 storage: add etcd storage
This patch adds etcd storage implementation. This should be useful in
environments where
- we dont want to depends on a separate, hard to maintain SQL cluster
- we dont want to incur the overhead of talking to kubernetes apiservers
- kubernetes is not available yet, or if kubernetes depends on dex
to perform authentication and the operator would like to remove any
circular dependency if possible.

Usage: sudo ./standup.sh [create|destroy] [etcd]
This is a script for standing up test databases. It uses systemd to daemonize
rkt containers running on a local loopback IP.
The general workflow is to create a daemonized container, use the output to set
the test environment variables, run the tests, then destroy the container.
sudo ./standup.sh create etcd
# Copy environment variables and run tests.
go test -v -i # always install test dependencies
go test -v
sudo ./standup.sh destroy etcd
