Eventing Integration

Now that preliminary eventing integration is complete, we would like to expand it to include a more interactive method for subscribing Functions to events. This will take the form of a prompt via the CLI (along with the assocaited Client API). This will require the creation of a server-side reporting mechanism for querying the list of available events, as well as the client-side prompts for displaying and choosing which events a given Function should be subscribed to.

Start by tracing the existing eventing integration through the CLI and Client API, then identify how server-side event discovery currently works. The work is complete when users can query available events and interactively choose subscriptions for a Function through the CLI and associated API.
