JSON Validation and Editing Improvements

[jdorn]

Background

We currently support JSON Schema to validate feature values, but JSON Schema is very difficult to write from scratch unless you are very familiar with it.

Also, when editing a JSON feature's value, we just render a simple textarea instead of taking the JSON Schema into account (e.g. if the schema says it's an object with a two string fields, we should render two text inputs, not a single textarea).

Features and Changes

This PR has 4 main changes:

1. If you have an existing JSON feature flag and go to add validation, we will infer the schema from the default value so you don't need to enter it from scratch
2. Added a new Simple Schema option for validation as an easier alternative to working with JSON Schemas (it compiles to JSON Schema under-the-hood)
3. Added a new easy-to-use JSON editing interface for feature values when Simple Schema validation is enabled
4. When entering JSON feature values manually, there is a new "format" link to fix any typos/formatting errors

TODO:

• Updated UI to show current validation settings on the feature page
• GUI for defining simple schemas (+ unit tests converting to JSON Schema)
• When adding validation to a feature for the first time, try to infer the initial simple schema from the feature's default value (+ unit tests)
• New editing UI for entering feature values when there's a simple schema
  • Default value
  • Force rule value
  • Rollout rule value
  • Experiment rule variation values (in RuleModal)
  • Experiment rule variation values (from experiment page)
• Add screenshots to PR
• Documentation
