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 list the WFS in the available layers, but not try to load it and show a warning if it's selected
• table: will not be displayed and show a warning instead
• 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 for this PR:

• add config param to doc
• tests

To-do for a separate PR:

• introduce pagination for table data

Architectural changes

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

Thank you! After testing this I was surprised to not see the WFS appear in the sources dropdown for the map preview.

I expected the WFS link to show up in the dropdown but when selecting it, that a warning appear telling me there's too many objects (like for chart and table).

Thanks for the review @jahow! You're right, that's what we said in the ticket. I've adapted the code accordingly.

Looks and works well! Please take a look at my comments, there seems to be an issue with the i18n:extract task... we can fix that in another PR but you should at least make sure we're not losing any translation when mrging this PR. Thank you!
