Revamped Hub Search

Meltano Hub needs to be revamped with the following feature updates:

• A search bar available when you first hit the Meltano Hub site.
• The search bar looks for exact word searches but also looks for keywords and descriptions (e.g. a search for Excel would turn up tap-spreadsheets-anywhere
• A details grid would be returned when searching that would allow for better readability of results as well as allow for filtering (preferably with a toggle interface).
