Create filters for list short URL

[bolovsky]

It would be nice to have the ability to filter URLs from list and to have a grouping mechanism, such as key or group that would allow one to have a contextful list returned

• Create group or key filter to act upon a new field, which is optional (must)
• Create start_date and end_date filter to act upon created_at (should)
• Create status filter to act upon the state of the short, checking by deleted_at or if a redirect happen (could)
