Vladimir Domnich b6b1644fd6 Refactor privileges for ssh commands
Remove logic that checks for root login and prepends command with sudo, because
we should not use root login at all and all commands (that require higher permissions
should be prefixed with sudo anyways).
Add sudo prefix to privileged commands that require it.
