Container stop event and etcd backend

[imacks]

stopped or removed containers are not removed from etcd backend. I had to hack together a bash script to remove all container data everytime, which is terrifying bad practice.

my fork

What I want to do here is to export all the data available from docker-gen to etcd, and keep it in sync. Then I am using confd to watch for changes.

Would it be possible to have a builtin way to export all docker api data to etcd effectively? Specifically, we need to generate a script that makes the necessary modifications to etcd data, such that it conforms to the current docker state (think dsc), and only do so when docker state changes.

For anyone with similar requirements, here's an updated solution.

Now it only update things that have changed.

Caveats:

• etcd complains about key not found. It doesn't affect the end result but just isn't pretty.
• sortObject doesn't work for port...probably need to implement int sort @rse
