Remove old files in deploy scripts #2500
Description
We do not delete old files now, so there are a lot of old files on our dev hosts (up to 3,5k). We need to remove old files from build and content/monitoring (embedded ui) and content/build (EM) folders
Script for embedded version: https://nda.ya.ru/t/O0-ib3247FpHJw
Script for EM: https://nda.ya.ru/t/d0ou7LDL7FpHPG
