[SUREFIRE-1460] Support @threadSafe in maven-surefire-report-plugin

**[Jeffrey Bennett](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=jbennett2091)** opened **[SUREFIRE-1460](https://issues.apache.org/jira/browse/SUREFIRE-1460?redirect=false)** and commented

It would be nice if the maven-surefire-report-plugin supported `@ThreadSafe` for the report-only goal. While typical use of this plugin is within \ (where I suspect threadsafety is of lesser concern), we happen to tie this plugin to the post-integration-test phase to insure that developers always have convenient index.html views of test results for how the build went. Developers are reluctant to add 'site' target as it generates a lot of reports they don't need when doing frequent builds, thus, having report-only as part of the regular lifecycle made sense for us.

Locate the maven-surefire-report-plugin implementation of the report-only goal and inspect how thread safety is declared for comparable Maven goals. Verify that report-only can support @ThreadSafe when used in the post-integration-test phase, while preserving its existing report generation behavior.
