Support Jasmine parallel mode

Is your feature request related to a problem? Please describe.
Starting from version 5, Jasmine can run specs in parallel. See here. Once we support it, we should expose reporterCapabilities: { parallel: true }.

Describe the solution you'd like
Two approaches we may take:

1. Set up the link between workers and the main process to pass Allure messages; process Jasmine events as they are reported.
2. Inject the Allure reporter into the worker itself. That may also work because Allure supports the independent handling of tests (test results combine naturally in the result folder). That's how Allure Mocha's support of parallel mode is implemented.
