infra: print log data when Python fuzz_target fails (#12502) 
## Description

This will make it easier to debug coverage failures that are not
reproducible locally.

The failure that I am trying to debug:
- https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=62231
-
https://oss-fuzz-build-logs.storage.googleapis.com/log-c420cf0c-f073-4c42-b75c-422971ef272e.txt

```
Step #5: Already have image (with digest): gcr.io/oss-fuzz-base/base-runner
Step #5: Entering python fuzzing
Step #5: Error happened getting coverage of fuzz_parse
Step #5: This is likely because Atheris did not exit gracefully
```

Similar log data is displayed in other blocks:

f716590249/infra/base-images/base-runner/coverage (L101-L105)


f716590249/infra/base-images/base-runner/coverage (L149-L153)


f716590249/infra/base-images/base-runner/coverage (L206-L210)


f716590249/infra/base-images/base-runner/coverage (L255-L260)

This PR is a continuation of
https://github.com/google/oss-fuzz/pull/12405 with a renamed branch to
avoid trial-build errors:

```
ERROR: (gcloud.builds.submit) INVALID_ARGUMENT: invalid build: invalid build tag "testing-cm/display-coverage-log": must match format "^[\\w][\\w.-]{0,127}$"
```

base-runner

Base image for fuzzer runners.

docker run -ti gcr.io/oss-fuzz-base/base-runner <command> <args>

Commands

Command Description
reproduce <fuzzer_name> <fuzzer_options> build all fuzz targets and run specified one with testcase /testcase and given options.
run_fuzzer <fuzzer_name> <fuzzer_options> runs specified fuzzer combining options with .options file
test_all.py runs every binary in /out as a fuzzer for a while to ensure it works.
coverage <fuzzer_name> generate a coverage report for the given fuzzer.

Examples

  • Reproduce using latest OSS-Fuzz build:
docker run --rm -ti -v <testcase_path>:/testcase gcr.io/oss-fuzz/$PROJECT_NAME reproduce <fuzzer_name>
  • Reproduce using local source checkout:
docker run --rm -ti -v <source_path>:/src/$PROJECT_NAME \
                    -v <testcase_path>:/testcase gcr.io/oss-fuzz/$PROJECT_NAME \
                    reproduce <fuzzer_name>
