There are a couple of things which interact badly with each other.
- Our management tools (Gauges, Status Page, and Metadata reloader Admin UI) only traverse one level of chaining metadata provider
- When multiple metadata provider files are present a chaining provider is silently grown to encompass all the files.
This means that if you have five providers in a singall file then you can see and manage 5 providers. If you add a single provider in a different file then you suddenly can only see two (one per file).
This is plain wrong. we need to change all our tools to recuse into all chaining providers.
