Liviu Rau 576d8f9418 [resultdb] Add more data about tests
Data added:
 - subtest_id as it is generated by Processors
 - processor_name to trace back the processors that generate subtests
 - path of the test
 - test_id suffixes introduced by processors:
   - numfuzz will have
     - an `analysis` suffix for analysis phase
     - a number suffix for the variants generated after analysis
   - variant processor adds a suffix for every variant
   - subtests will inherit suffixes from the parent tests (origin)
