Creating a Labs service for Presentation Solutions

[clintandrewhall]

Summary

Branch includes pre-requisite changes from #96185

This is a first attempt at an Labs Service and enablement UI for Canvas and Dashboard.

We have a number of projects coming up that would benefit from being a part of master with a feature flag for testing and evaluation with stakeholders. While there are a number of discussions and even long-term plans for such a system globally provided within Kibana, our need is more immediate, so creating an easily replaceable/alterable service within presentation_util made sense. It's also a good way to demonstrate our needs while those discussions take place.

Features

• This system uses our abstracted service model to provide an API to the React layer.
• The ProjectConfig allows for a number of options:
  • isActive: whether the experiment is "flipped" in master by default;
  • environments: determines where flags can be set, (see "Environments", below);
  • solutions: determines to which solutions a project applies. This is useful for constraining the list of Projects in the LabsFlyout depending on where it is shown, (see "UI Components", below).

Environments

Projects can be enabled or disabled in a number of environments:

• isActive: in the ProjectConfig, we can make an experiment "on by default" in code. It would be expected that this "flip" would be the first step towards removal of the project and its related branches
• kibana: this corresponds directly to a uiSetting flag.
• browser: sets the flag in localStorage of the browser instance. This means this flag persists after the browser is closed, (but only to the specific Kibana instance).
• session: sets the flag in sessionStorage of the browser instance. This means the flag is reset whenever the tab or window is closed.

IMPORTANT: if the project has any branched code on the server, browser and session should not be allowed in the config. We should try to avoid branching in that way, however, opting instead for clean API paths that are invoked from the client.

UI Components

I created a "starting place" for lab project management in a EUIFlyout that can be placed in any solution that has the presentation_util context enabled. There is also a starter "Beaker Button" that demonstrates how to use the flyout. There are complete Storybook implementations for testing and iteration purposes.
