🎩 What? Why?

This PR introduces the management of filters for participatory spaces based on taxonomies.

The main approach is the creation of the concern Decidim::Admin::HasTaxonomyFilters that needs to be included in the final controller that wants to make use of it. In the controller is necessary to define the manifest name for the participatory space.

Todo:

• Given that I am an admin configuring a process or an assembly, when I go to admin/processes or admin/assemblies, then I see a page called 'Taxonomy filters' from the dropdown menu.
• Given that I want to add a new taxonomy filter, when I click on the button 'Add taxonomy filter', then I should see a page with a dropdown of all available taxonomies, and when I choose one, I can deselect any taxonomies I don't want to use in the filter
• Given that I want to assign a taxonomy to a process or an assembly based on the filters created, when I go to its configuration form, then I see a field for every filter created.
