Search through library should use backend side implementation

[orontee]

With current implementation, search happens locally in the currently visited directory.

See https://docs.mopidy.com/en/latest/api/core/#mopidy.core.LibraryController.search

• Add a model class for artists
  Since search results may contain albums, artists or tracks.
• Add a library search action and extend model with search results
• The search should be performed in a task and must be cancelable
• UI to display search results
• Setting to customize search query

UI draft

Displayed when entering search mode (by clicking search button or corresponding shortcut).
Page made of stack widget with:

• A page made of a single centered label for "no result to display so far".
• A page made of a progress bar for "ongoing search" (with a cancel button?)
• A page for results with three sections albums, artists and tracks
• Clicking on an album should enter the corresponding library view
• Clicking on a track should enqueue/play (?) that track
• Clicking on an artist should enter an artist view
• Access to all album or tracks results

Questions left opened / Remarks

The interest of using the backend side search implementation is very limited when using Mopidy-Local, see
mopidy/mopidy-local#16.

How-to search locally in currently visited directory?

How-to disable some Mopidy backends? Should we care?

How-to choose search criteria? Should we care?
