Revert of New run shell implementation for DeviceUtils

Revert of New run shell implementation for DeviceUtils (patchset #8 id:140001 of https://codereview.chromium.org/659533002/)

Reason for revert:
Broke some telemetry telemetry unittests and perf unittests

Original issue's description:
> New run shell implementation for DeviceUtils
>
> The main differences are:
> - it uses AdbWrapper.Shell to actually execute the command.
> - when the cmd is supplied as a list of a command and its arguments,
>   the arguments are quoted to prevent them from being (mis)interpreted
>   by the shell.
> - a new single_line option to check that the output produces contains a single line, and return the value of that line.
