Provide deployment information to ecl watch for it to display

Currently it can be hard to determine the azure subscription/deployment from ecl watch - which is useful for gaining more information about a cluster when something goes wrong. (E.g. it is currently required to access any logging information for a cluster.) We should provide a mechanism for proving information in the helm chart that can be reported to eclwatch when it first connects and then displayed in the about or similar.
