tradefed: Add DisableSELinuxTargetPreparer

Some tests require SELinux to be disabled prior to executing and
re-enabling afterwards. At the same time not all devices have
SELinux enabled (like gce devices), therefore if it's not already
disabled, no-op.

Bug: 117574441
Test: Unitests
Test: atest libiorap-java-tests against marlin & gce_cf

Trade Federation (TF / tradefed)

TF is a test harness used to drive Android automated testing. It runs on test hosts and monitors the connected devices, handling test scheduling & execution and device management.

Other test harnesses like Compatibility Test Suite (CTS) and Vendor Test Suite (VTS) use TF as a basis and extend it for their particular needs.

Building TF:

  • source build/envsetup.sh
  • tapas tradefed-all
  • make -j8
