This PS resolves several issues in database backup script in HTK chart:
- decreases random delay before uploading remote backup to up to 30s
- removes additional random delay before remote backup verification
- switches remote backup verification protocol from sha256 to md5
The main goal for the changes above is decreasing network load on remote
backup storages by eliminating the need of remote file download right
after uploading in order to be able to calculate sha256 checksum.
