Support importing other TEST_MAPPING files

This change allows atest to handle TEST_MAPPING files containing imports,
for example:
  "imports": [
    {
      "path": "../folder2"
    }
  ]
atest shall search for TEST_MAPPING files in the imported path and its
parent directories and include all tests found for the given test group.

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
