This upgrades x-pack dependencies to the following versions:
* `redux@4.0.0` (to support TypeScript in the upcoming infra-ui migration, `redux-observable@1.0.0` in particular)
* `redux-thunk@2.3.0` (to support `redux@4.0.0`)
* `react-redux@^5.0.7` (to support `redux@4.0.0`)
**Interface changes**
There are two goals behind the interface changes:
* Make it clearer which courier modules are meant for public consumption by exporting them from the top level.
* Simplify the courier object by removing responsibilities and focusing its responsibility solely on scheduling search requests via the fetch method and timefilter.refreshInterval Angular event.
I did this by taking the following steps:
* Removing redirectWhenMissing, indexPatterns, SearchSource, and SavedObject from the courier object. I also removed some unused methods from its interface.
* redirectWhenMissing is now a service registered on the kibana/url Angular module.
* indexPatterns is now a service registered on the kibana/index_patterns Angular module.
* SearchSourceProvider and SavedObjectProvider are now top-level exports of ui/courier.
* migrateFilter, decorateQuery, buildQueryFromFilters, and luceneStringToDsl are now top-level exports of ui/courier.
**Internal changes**
I also made some internal changes in an effort to organize the code clearly and reduce unnecessary complexity.
* I refactored the async code in CallClient to appear sync with async/await and encapsulated chunks of logic in helper functions. I also used an isAborted flag instead of overwriting the esPromise var with an enum.
* I combined Looper and SearchLooper into a single class and deleted unused functions.
* I reorganized the courier/fetch/request code into SearchRequest, SegmentedSearchRequest, and serializeFetchParams modules.
* Renamed various other methods and variables to improve clarity.
When running the optimizer in dev mode, with new or updated entry files, the optimizer will run once and then a second time immediately after. This is because the webpack watcher uses really loose timestamp checks and since the entry files are created immediately before initializing the optimizer they are considered to be "changed" even when they aren't. To avoid this I've integrated the `webpack.WatchIgnorePlugin` to ignore the entry files from the watcher.
This could also be fixed by modifying the timestamps of the files after writing them to disk, but I didn't want extra FS access and it's not actually possible to change the entry files without completely restarting the optimizer.
