* [@kbn/expect] "fork" expect.js into repo
* [eslint] autofix references to expect.js
* [tslint] autofix all expect.js imports
* now that expect.js is in strict mode, avoid reassigning fn.length
* [Stats API] Set API field names per spec
* fix jest tests
* fix api integration test
* trash the original metrics collector
- constantly accumulating stats over time does not align with the existing behavior, which is to reset the stats to 0 whenever they are pulled
* move some logic out of the collector types combiner into inline
- change the signature of sourceKibana
* Make a new stats collector for the API
- to not clear the data when pulling via the api
- fetching is a read-only thing
* isolate data transforms for api data and upload data
* no static methods
* remove external in bytes
* remove the _stats prefix for kibana and reporting
* update jest test snapshot
* fix collector_types_combiner test
* fix usage api
* add test suite todo comment
* reduce some loc change
* roll back mysterious change
* reduce some more loc change
* comment correction
* reduce more loc change
* whitespace
* comment question
* fix cluster_uuid
* fix stats integration test
* fix bulk uploader test, combineTypes is no longer external
* very important comments about the current nature of stats represented and long-term goals
* add stats api tests with/without authentication
* fix more fields to match data model
* fix more tests
* fix jest test
* remove TODO
* remove sockets
* use snake_case for api field names
* restore accidental removal + copy/paste error
* sourceKibana -> getKibanaInfoForStats
* skip usage test on legacy endpoint
* fix api tests
* more comment
* stop putting a field in that used to be omitted
* fix the internal type to ID the usage data for bulk uploader
* correct the kibana usage type value, which is shown as-is in the API
* more fixes for the constants identifying collector types + test against duplicates
* add a comment on a hack, and a whitespace fix
* Move all reporting tests into their own folder to allow for multiple kibana.yml configuration tests, including chromium
* Add debugging and try to skip other tests an jenkins to speed things up
* More debug output
* more logging (remove other line which failed on jenkins)
* Remove no sandbox flag, it doesn't help
* Add fix for socket hangup and clean up tests
* fix path to logstash_functional
* Extend timeout for chromium, add verbose logging, add better comment, conditionally output curl command
* fix path... again
* Ah, other functional tests still need access to reporting page object, put it back
* fix sp err
* Add debug logs for screenshot stitching for png.bitblt error
* Fix tests that don't pass logger to screenshotStitcher
* Fix logger being undefined
* Add more debug output
* png has data, too much info to spit out
* Add comment with link to issue for extra debug messages so they can be left in since so many passes
* Dont use spawnSync with curl, use http.request instead, more support for it
* Comment out chromium tests for now to avoid flakiness
* Wait... lets at least make sure the other fix worked (the http.request instead of spawnsync and curl)
* New http.request code doesn't seem to work on jenkins, timing out after 10 secs maybe
* go back to spawnsync to see if it's an issue with the rxjs code or the http.request code
* I think I figured it out...
* Comment out tests to avoid flaky png error in the screenshot stitcher
* Use a const for OSS archive path
* use path.resolve correctly.
