Analytics event tracking

[bodom0015]

Problem

We currently have no way of tracking user actions within the system. That is, given a set of users exercising the system, we are unable to track history of which applications were run or which actions were performed.

Moreover we have no way of knowing when users are encountering issues with a particular application.

Fixes #294

Approach

Add simple event tracking to monitor which buttons the user pushes on the Workbench Dashboard.

We can now track:

• page views (present previously)
• adding an application from the catalog
• deleting your instance of an application
• starting / stopping an application
• viewing logs/config/console for an application's service
• editing an application's service

NOTE: If we can think of other low-hanging analytics to track here, I am open to further suggestions 👍
