Run arbitrary Tast tests.

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.Pass ${DUT} tast.generic
    test_that --args=tast_expr='("group:mainline")' ${DUT} tast.generic
    test_that --args='tast_expr=example.RuntimeVars tast.example.strvar="Hello_World"' ${DUT} tast.generic
