Allow to set a cache duration

[Dan]

Situation

The package allows developers to cache certain endpoints, for example via annotations.

Cached items have no specific cache duration. To invalidate the cache editors need to clear the cache:

The cache will only be cleared if the "clear cache" button is klicked in the backend.

However, a typical use cace for API endpoints is to cache requests for a short period of time only. For example 1 hour or even only 1 minute for items with a high change frequency.

Feature Request

Allow to set a cache duration time via annotation as well.
