[testing/bazel] Make the functest harness configurable
This commit replaces util/opentitantool_test_runner.sh with a test
runner script that takes an arbitrary test harness (besides
opentitantool).
It also adds parameters in Bazel to allow this to be specified on a
per-test basis in preparation for E2E tests.
