Datahub: Allow to set a feature limit for WFS

[tkohr]

Description

This PR introduces a new max_feature_count configuration. This allows to set a limit of WFS features to be displayed on the map, table and chart preview. If a number is set here and a WFS resource exceeds it, the

• map: will not propose the WFS layer to be displayed (removed from drop-down)
• table: will paginate the queried data by the max_feature_count number => still todo
• chart: will not be displayed and show a warning instead

The goal of the PR is to improve performance and display consistent results on big datasets, where the backend might only respond with a limited number of features.

To-dos:

• paginate table data
• tests

Architectural changes

The PR has refactored the record-metadata.component and extracted relevant code for the preview section into a record-data-preview.component.
