In SQuaSH, the drill down mechanism associates one or more metrics with a bokeh app. A bokeh app can have several plots, etc

For example, the drill down plots for AM1, AM2 metrics are implemented in the AMx bokeh app.

The mapping between metrics to bokeh apps should be done in a process called "application registration" . Other things may happen during that process like spinning up a bokeh server container for the new app, or adding the new app to and existing bokeh server container.

This process will make it easier for developers to add new bokeh apps to SQuaSH.
