CE-3266: Enable disable features

The use of individual features can be enabled and disabled through configuration, and it can also be overridden by the admin via a REST API.

Example configuration: features.enabled.ioc.createIoc=false

Feature flag toggle endpoint:

• Request method: PUT
• Request URL: /api/v1/features
• Open API path: Features.toggleFeature

Request body example:

{
  "tagName": "ioc",
  "operationName": "createIoc",
  "featureState": "DISABLE"
}

By default every feature is enabled.
