Write log paths and types to report

Acloud writes the log paths and types to the creation report. In the
automated tests, TradeFed can read the entries and upload to logging
services. This feature will replace the hardcoded paths in TradeFed.

Test: acloud-dev create --avd-type goldfish \
      --local-image --local-instance -vv --report-file ~/report.json
