AY-7020_Autoupdater is not ready for specific dependency and addons paths

[iLLiCiTiT]

Issue

Distribution has few issues. The most important at this moment might be that it downloads addons, dependency packages and launcher if it does not find it, but at the same time does not validate if other process does it too, so there might be clashes. Thath can happen when 2 processes of ayon are started and both should update, or when 2 different machines are pointing to the same location.

Possible solution

Low hanging fruit fix would be that installation (download and extraction) happens to different folder and only the last step would move it to final location only if is not there yet.

Proper solution would be to create "distribution file" (similar to lock file) before we start download and distribution. The lock file should be looked for before download and update. Other process wanting to download the same thing should wait, they have to find out if they should wait (for cases the distribution fails in other process) so the distribution file should be also updated with progress, in case progress was not updated for some time, the other process can force download and create new distribution file.

The proper solution is more complex and requires major modifications in current distribution logic.
