write its addresses to jenv/environ info/connection info.

Set a machine's tools version when the agent starts

Fixes: https://bugs.launchpad.net/juju-core/+bug/1359800

The referenced bug shows an error initialising container support when a machine's agent starts up.

2014-08-20 22:06:07 ERROR juju.provisioner container_initialisation.go:154 cannot get tools from machine for lxc container
2014-08-20 22:06:07 ERROR juju.provisioner container_initialisation.go:95 starting container provisioner for lxc: initialising container infrastructure on host machine: agent tools for machine 5 not found
2014-08-20 22:06:07 ERROR juju.worker runner.go:218 exited "5-container-watcher": initialising container infrastructure on host machine: agent tools for machine 5 not found

The only way I can see that happening is if the container worker starts before the upgrade work sets the tools version. That can happen as both upgrade worker and container worker start up in parallel.

I moved the logic to set the tools version on a machine from the upgrade worker to the agent's APIWorker() method, thus ensuring the tools version is set early before it is needed.

I also found what looks to be bad logic in the container initialisation worker - the code to stop the worker was duplicated and one of the copies was called in the wrong place; it looked like the worker was terminated after the first container type was handled, meaning subsequent container types added to the machine may not have been started properly.

Merge pull request #605 from howbazaar/state-env-tag-always-set

Ensure that environTag is always set on state.State when Opened

When we Open state we need to set the environment tag.

Previously the environment tag was only specified when the database was initialized.  Now we set it every time the database connection is opened.  This is required for when we have multiple environments, and we want to filter the results based on the current environment.

A follow-up branch will update this tag based on the environment uuid from the api server when passing the state connection to the facades of the API server.
