Run arbitrary Tast tests with servo support.

Tast is an integration-testing framework analagous to the test-running portion
of Autotest. See https://chromium.googlesource.com/chromiumos/platform/tast/ for
more information.

This test runs arbitary Tast-based tests specified by args given to test_that.
This test might be useful on debugging to simulate Tast test runs invoked via
Autotest.

Examples:
    test_that --args="tast_expr=example.ServoEcho servo_host=${SERVO_HOST}
            servo_port=${SERVO_PORT}" ${DUT} tast.generic-servo
    test_that --args="tast_expr='(\"group:mainline\")' servo_host=${SERVO_HOST}
            servo_port=${SERVO_PORT}" ${DUT} tast.generic-servo
    test_that --args=tast_expr='("group:mainline")' ${DUT} tast.generic-servo
