bazel: Code coverage does not honor "exclusive" tag

Description of the problem / feature request:

I have tests marked as exclusive, and when I run bazel test //..., they run serially. When I run with code coverage:

bazel coverage //... \                                           
--combined_report=lcov \
--coverage_report_generator=@bazel_tools//tools/test/LcovMerger/java/com/google/devtools/lcovmerger:Main \
--experimental_java_coverage && genhtml -o coverage bazel-out/_coverage/_coverage_report.dat && open coverage/index.html

they run in parallel.
