Added GPIO support for update engine automated test.

New functionality in update engine for discovering and reading the
dut_flaga/b GPIOs; we use the dut_flaga value as trigger for using
a different update server URL.

Note: in the future, we will migrate all GPIO functionality outside of
update engine, into its own dedicated package.
