[blocked]Add filter interface to any filterable resource view

Currently, the only way to add filters to resource view is when they're inside a `ckanext-dashboard`. Ideally, we could add these filters anywhere a filterable resource view is displayed.
That's because we're doing a full-text search query, which only work on textual fields. We have a few options to make it work with other field types. We could:

### Create FTS indexes for all types

To do so, we'll need to convert the columns to text and index them. Depending on the type of data, this work relatively well but, we have to keep in mind that as we can't (currently) do queries for substrings in the middle of a string. This might be a problem for some types of data.

Just to add a example of what that might look like, see:
