Support Test Collation in Deployment Task

We have plugin in the Marketplace that runs Selenium Tests. Most folks prefer to run the selenium tests after they have deployed code to some environment. This is particularly true after a complete deployment task. The problem however is Bamboo has no way of reporting test reports in deployment plans. Also when we try to run our plugin, we find that testCollationService.collateTestResults(taskContext, testFilePattern, new MyUnitTestReportCollector()) fails. This is because CommonTaskContext type is not supported for this method in place of TaskContext type. Please make this available for DeploymentPlans. Also allow JUNIT type results displayable for deployment plans.
