Replace Desktop Kit with LXD solution

[Michael Sheldon]

The new "Ubuntu SDK Desktop Kit" appears to be missing most QML imports besides the core UITK and Qt ones. From a quick test it appears to be missing at least:

Ubuntu.Connectivity
Ubuntu.Content
Ubuntu.DownloadManager
Ubuntu.OnlineAccounts
Ubuntu.Web
Ubuntu.Thumbnailer
U1db

Which prevents many applications from being usable with the kit.

This is incredibly annoying while developing the music-app, currently I cannot run the music-app on the desktop until I upgrade to 16.04.

This is because the music-app depends on mediascanner2, media-hub and thumbnailer. All of which are not installed in the ubuntu sdk desktop kit.
Furthermore I cannot install these packages on the 'desktop' and use the 'desktop' kit, due to it using the new background playlists which support was backported/included in QtMultimedia 5.6, which is not included in Wily as it is of a greater Qt version.

So we need to be able to install extra packages into the Ubuntu SDK desktop kit :-) Or I hope future solutions, such as the possible route of LXD will allow this?

The fix for this is actually to remove the desktop kit as we are not able to provide the correct experience there.

@Andrew

The Ubuntu Desktop Kit is made for UI prototyping and it contains a limited set of Qt APIs. Please keep in mind that it is technically impossible to backport _ALL_ platform APIs of the latest OTA images to 14.04 desktop. That would require to rebuild and repackage almost the whole archive.

If you want to understand more how Kits are made and what they are for please read this blog post: https://developer.ubuntu.com/en/blog/2015/03/18/everything-you-always-wanted-know-about-kits-were-afraid-ask/

At the moment if you want a desktop runtime environment your only option is to be at least on 16.04.

The ultimate and permanent solution will be indeed the LXD based build and runtime Kit. The LXD containers will do contain all APIs and all runtime tools. So the SDK will be totally decoupled from the host desktop.

I changed the title so lets continue to track this bug
