Summary:
This diff cleans up some cruft and adds some features:
* It removes the usage of an env variable to control workers.
* It removes the lazy and handwavy calculation on how many workers to use for jest-haste-map. Jest itself uses the maximum amount of workers available and it has never been reported as an issue – especially since it is a one-time startup cost of about 3 seconds on a cold cache only.
* It adds a `--max-workers` flag to replace the env variable. This one is able to control both the number of workers for `jest-haste-map` as well as the transformers.
* It makes the transformers run in the parent process if 1 or fewer workers are are specified. This should help with debugging.
Once you approve this diff, I will publish a new version of metro to npm and update the version used in RN and remove the use of the env variable altogether: https://our.intern.facebook.com/intern/biggrep/?corpus=xplat&filename=&case=false&view=default&extre=&s=REACT_NATIVE_MAX_WORKERS&engine=apr_strmatch&context=false&filter[uninteresting]=false&filter[intern]=false&filter[test]=false&grep_regex=
Note: the process of adding a CLI option is really broken. Commander also has a weird API. We should consider building a better public API for Metro and then consider how to build a new CLI on top of it and simplify our internal integration. I really don't like how Metro is integrated across pieces of the RN cli in ways that is hard to manage. But that is a larger task for another time :)

Summary:
ericvicenti Here is the latest updates and fixes for the container testing. Everything should be good to go now, the update for `inotify.max_user_watches` should fix the E2E test issues you were seeing locally.
The update to the packer prevents excessively large filename lengths due to the hash used in the name and splits them into directories instead. I was getting errors locally on the E2E because the hash filename was over 248 characters which was causing issues on the base image file system. It might not have appeared in circle due to another file system being used with different limits. I can separate it out into another PR if you want though.
* Turned jenkins instrumentation parallelism up to 3
* Disabled various instrumentation tests that seemed to have inconsistent results from
Jenkins by default
* Install google-chrome in the android base image so the chrome debug E2E test does not fail
* Turned back on E2E tests

Summary:
ericvicenti - Here are necessary updates for the the testing container workflow.
normanjoyner
Temporarily disabled E2E tests on the Containership Jenkins pipeline because they seemed to be sporadically failing and slow down the run rate of CI tests.
* Run all stages and parallel branches in testing suite even if one
fails (just mark the overall job as failed)
* Added update to docker tag name to convert spaces to hyphens to cover
edge case where the project name may have spaces
* Updated buck to more recent version in the base image
* Remove duplicate module provider from `.flowconfig`
* Correctly exit with status code from failed instrumentation tests
* Add JSCHeaders to prepare for testing on stage branches
* Fix bug in filtering of failed instrumentation tests
* Turn down retry count to 1 for E2E tests and temporarily disable
* Add retry3 count to the apk install from buck
* Updated base image to install android SDKs through grepping since the
IDs update frequ

Summary:
Created a containerized environment to run unit and integration tests for both javascript and android as well as a Jenkinsfile using the new 2.0 Pipeline syntax for integration into a Jenkins CI cluster.
Here is a quick summary of the changes:
* The android image is built from two separate dockerfiles. There is a base image that handles the heavy lifting of dependencies that are infrequently changed while the secondary image extends the base and allows for much quicker incremental builds on code updates.
* The javascript image is simple and is relatively quick to build, therefore there is no base image for any react specific javascript dependencies and it is all packaged in a single docker image.
* A new `scripts/docker` has been created including some javascript files and shell scripts to aid in the running of the tests
* The instrumentation test runner script can be passed various flags to control which tests run since the entire suite takes a significant amount of time to run synchronously
* Jen
