As an app developer, I want to be able to filter by the asset fields

Problem Definition

Today, the filtering options for assets are limited to the options listed in the query parameter of the GET /rest/assetapi/asset/search REST API endpoint. This doesn't cover the ability to filter for one or more specific fields.

Suggested Solution

Add the ability to filter on the additional fields that can be defined for an asset.

Workaround

While this will not achieve the goal because it doesn't provide the ability to search on a specific field, the current search can be used if the values are also present as label, origin and fields.
