Run many tests in parallel

- Most tests under analytics_util and cmd touches global variables
  so they weren't touched.
- cmdline had similar issues but with environment variables.
- cipd tests use Bootstrap() which is not concurrent safe.
- project tests use non hermetic temporary environment to run tests, and
  furthermore can corrupt the current checkout commit history if run in
  parallel.
