Adding filtering and sorting options to listing user profiles endpoint

[mario-nt]

The API endpoint for getting the list of user profiles can be improved by accepting the filter and sort query params to allow users to filter and sort user profiles.

Example: http://localhost:3001/users?search=john+doe&pageSize=50&page=1&filter=email+verfied&sorting=UploadedAsc

Ideas for filtering users:

• Email verified
• Email not verified
• Admin user
• Non admin user
• Bio?
• Avatar?
• Has uploaded torrents?
• Date registered (Past year)
• Date registered (This month)

Ideas for sorting users:

• Date registered (Newest first)
• Date registered (Oldest first)
• Username (A → Z or Z → A)
• Number of torrents uploaded (Asc or Desc)

This list can be improved in the future if we add additional info for the users such as new roles (moderator), comments...

Also, a really nice sorting idea would be based on seeding/leeching ratio.

But as a first iteration, I would implement the following which I think are the most useful for admin users:

Filtering

1. Email verified
2. Email not verified
3. Has uploaded torrents

Sorting

1. Date registered (Newest first)
2. Date registered (Oldest first)
3. Username (A → Z or Z → A)
4. Number of torrents uploaded (Asc or Desc)
