<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes are part of #11091

<!-- Either: -->
- [X] There are tests for these changes at my [gh-pages](https://github.com/creativcoder/gsoc16/tree/gh-pages) branch to test  the instantiation of service workers by their manager, but will need to discuss how that would integrate into master.

Changes:
- Introduces a `ServiceWorkerManager`, which maintains an map of registered service workers as well as a map of active workers keyed by their `scope_url`.
- Adds the initialization of ServiceWorkerManager, at the `script::init()`, which makes it available as a single entity listening for requests from different script threads.
- Adds a timeout thread in `serviceworkerglobalscope`, which terminates the workers, after a timeout of 60 secs, thereby removing it from the active workers list.
- Adds the matching of scope urls, in longest prefix way rather than path structural way, according to [spec](https://slightlyoff.github.io/ServiceWorker/spec/service_worker/#scope-match-algorithm).
- Make ServiceWorkerManager, the holder of network sender, instead of script thread, so it can send `CustomResponse`.

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
