/**
 * This define a Jenkins step "bazelJob" that write a rc file, execute shell configuration steps,
 * run build and test with bazel and publish the XML reports.
 * Each arguments is set by a variable in the body of the step and the list of possible arguments
 * is:
 *   - binary: the path to the bazel binary
 *   - targets: list of targets to build
 *   - tests: list of targets to test
 *   - configuration: list of shell step to configure the project
 *   - build_opts, test_opts: option for build and test (build options also applies for tests)
 *   - extra_bazelrc: extraneous content for the rc file, will go after all other options.
 *        Generally to be provided as a parameter of the job.
 *   - stage_name: Name of the stage, for prefixing substages
