Add a coverage-report flag that will cause the sandbox to generate a coverage report (with suffix .cov) in the debug log directory upon exiting. For the report to be generated, runsc must have been built with the following Bazel flags: `--collect_code_coverage --instrumentation_filter=...`. With coverage reports, we should be able to aggregate results across all tests to surface code coverage statistics for the project as a whole. The report is simply a text file with each line representing a covered block as `file:start_line.start_col,end_line.end_col`. Note that this is similar to the format of coverage reports generated with `go test -coverprofile`, although we omit the count and number of statements, which are not useful for us. Some simple ways of getting coverage reports: bazel test <some_test> --collect_code_coverage \ --instrumentation_filter=//pkg/... bazel build //runsc --collect_code_coverage \ --instrumentation_filter=//pkg/... runsc -coverage-report=dir/ <other_flags> do ...
