addon-watch command for developer mode where we can make the forge container watch for rebuilds of addons and auto-reload them

its kinda clumsy and slow when working on a Forge addon; you try some code, rebuild it, then in your Forge app you run the remove / install commands to get the new code into your CLI install of Forge (or your web app running Forge, or your IDE etc...)

What would be cooler is if we had an 'addon-watch wildcard' command. That lets you start/stop watching addons that have SNAPSHOT versions. Even ignore the wildcard and just watch all SNAPSHOT addons.

When watching, every installed addon of version SNAPSHOT, we'd watch ~/.m2/repository for the builds of the addons. If you then rebuild an addon, it'd reload the addon automatically (remove it first, then re-install it)!

This would make it much quicker and simpler to try things out! Its especially painful when testing out changes to Forge commands in a web app (e.g. hawtio-forge) as you typically need to build the addons then rebuild the addon repo then rebuild/restart the web app etc!

So this simple approach would help folks get more rapid feedback on building any addon - however you run them (CLI, web, IDE)
