Sergiy Markin 13c1d8cd38 [backups] Add throttlling of remote backups
This PS adds a possibility to limit (to throttle) the number of
simultaneously uploaded backups while keeping the logic on the client
side using flag files on remote side. The main idea is to have an
ability to limit number of simultaneous remote backups upload sessions.
