Change the Feature Flag list view to show Environments

Release notes

Problem to solve

Currently, the user interface that displays a list of feature flags shows the full strategy information for each feature flag. This information can be overwhelming, and often breaks the visual flow of the interface, making it more difficult to grok.

Proposal

Pair down the user interface by showing the feature flags impacted by a feature flag strategy:

Note, there is a limit to the amount of space environments can fill up. Two things to consider here:

  1. Similar to the environments page, environments that are grouped (like Review Apps) should be displayed as one large environment with a + symbol.
  2. If the space for environments is exceeded, we add a + 23 more at the end of the line. MVC, this doesn't do anything specific.

Future Iterations

We should include popover information specific to the strategy related to that environment.
