After testing, it seems that the flakyness we are experiencing in our legacy
saucelabs job is caused by timeouts which happen due to the karma server being
unable to serve all of the files needed for the tests fast enough while concurrent

versions of AngularJS (v1.5+). Previously, we only ran them against
v1.5, v1.6 and v1.7.

In the Angular Package Format, we always shipped UMD bundles and previously even ES5 module output.
With V10, we removed the ES5 module output but kept the UMD ES5 output.
For this, we were able to remove our second TypeScript transpilation. Instead we started only
building ES2015 output and then downleveled it to ES5 UMD for the NPM packages. This worked
as expected but unveiled an issue in the `@angular/core` reflection capabilities.
In JIT mode, Angular determines constructor parameters (for DI) using the `ReflectionCapabilities`. The
reflection capabilities basically read runtime metadata of classes to determine the DI parameters. Such
metadata can be either stored in static class properties like `ctorParameters` or within TypeScript's `design:params`.
If Angular comes across a class that does not have any parameter metadata, it tries to detect if the
given class is actually delegating to an inherited class. It does this naively in JIT by checking if the
stringified class (function in ES5) matches a certain pattern. e.g.
```js
function MatTable() {
var _this = _super.apply(this, arguments) || this;
```
These patterns are reluctant to changes of the class output. If a class is not recognized properly, the
DI parameters will be assumed empty and the class is **incorrectly** constructed without arguments.
This actually happened as part of v10 now. Since we downlevel ES2015 to ES5 (instead of previously
compiling sources directly to ES5), the class output changed slightly so that Angular no longer detects
it. e.g.
```js
var _this = _super.apply(this, __spread(arguments)) || this;
```
This happens because the ES2015 output will receive an auto-generated constructor if the class
defines class properties. This constructor is then already containing an explicit `super` call.
```js
export class MatTable extends CdkTable {
constructor() {
super(...arguments);
this.disabled = true;
}
}
```
If we then downlevel this file to ES5 with `--downlevelIteration`, TypeScript adjusts the `super` call so that
the spread operator is no longer used (not supported in ES5). The resulting super call is different to the
super call that would have been emitted if we would directly transpile to ES5. Ultimately, Angular no
longer detects such classes as having an delegate constructor -> and DI breaks.
We fix this by expanding the rather naive RegExp patterns used for the reflection capabilities
so that downleveled pass-through/delegate constructors are properly detected. There is a risk
of a false-positive as we cannot detect whether `__spread` is actually the TypeScript spread
helper, but given the reflection patterns already make lots of assumptions (e.g. that `super` is
actually the superclass, we should be fine making this assumption too. The false-positive would
not result in a broken app, but rather in unnecessary providers being injected (as a noop).

In the current version of zone.js, zone.js uses it's own package format, and it is not following the rule
of Angualr package format(APF), so it is not easily to be consumed by Angular CLI or other bundle tools.
For example, zone.js npm package has two bundles,
1. zone.js/dist/zone.js, this is a `es5` bundle.
2. zone.js/dist/zone-evergreen.js, this is a `es2015` bundle.
And Angular CLI has to add some hard-coding code to handle this case, o5376a8b139/packages/schematics/angular/application/files/src/polyfills.ts.template (L55-L58)
This PR upgrade zone.js npm package format to follow APF rule, https://docs.google.com/document/d/1CZC2rcpxffTDfRDs6p1cfbmKNLA6x5O-NtkJglDaBVs/edit#heading=h.k0mh3o8u5hx
The updated points are:
1. in package.json, update all bundle related properties
```
"main": "./bundles/zone.umd.js",
"module": "./fesm2015/zone.js",
"es2015": "./fesm2015/zone.js",
"fesm2015": "./fesm2015/zone.js",
```
2. re-organize dist folder, for example for `zone.js` bundle, now we have
```
dist/
bundles/
zone.js // this is the es5 bundle
fesm2015/
zone.js // this is the es2015 bundle (in the old version is `zone-evergreen.js`)
```
3. have several sub-packages.
1. `zone-testing`, provide zone-testing bundles include zone.js and testing libraries
2. `zone-node`, provide zone.js implemention for NodeJS
3. `zone-mix`, provide zone.js patches for both Browser and NodeJS
All those sub-packages will have their own `package.json` and the bundle will reference `bundles(es5)` and `fesm2015(es2015)`.
4. keep backward compatibility, still keep the `zone.js/dist` folder, and all bundles will be redirected to `zone.js/bundles` or `zone.js/fesm2015` folders.

In the past we had connecitivity issues on Saucelabs. Browsers on
mobile devices were not able to properly resolve the `localhost`
hostname through the tunnel. This is because the device resolves
`localhost` or `127.0.0.1` to the actual Saucelabs device, while it
should resolve to the tunnel host machine (in our case the CircleCI VM).
In the past, we simply disabled the failing devices and re-enabled the
devices later. At this point, the Saucelabs team claimed that the
connecitivy/proxy issues were fixed.
Saucelabs seems to have a process for VMs which ensures that requests to
`localhost` / `127.0.0.1` are properly resolved through the tunnel. This
process is not very reliable and can cause tests to fail. Related issues have been
observed/mentioned in the Saucelabs support docs. e.g.
https://support.saucelabs.com/hc/en-us/articles/115002212447-Unable-to-Reach-Application-on-localhost-for-Tests-Run-on-Safari-8-and-9-and-Edgehttps://support.saucelabs.com/hc/en-us/articles/225106887-Safari-and-Internet-Explorer-Won-t-Load-Website-When-Using-Sauce-Connect-on-Localhost
In order to ensure that requests are always resolved through the tunnel,
we add our own domain alias in the CircleCI's hosts file, and enforce that
it is always resolved through the tunnel (using the `--tunnel-domains` SC flag).
Saucelabs devices by default will never resolve this domain/hostname to the
actual local Saucelabs device.

This commit changes the Angular compiler (ivy-only) to generate `$localize`
tagged strings for component templates that use `i18n` attributes.
BREAKING CHANGE
Since `$localize` is a global function, it must be included in any applications
that use i18n. This is achieved by importing the `@angular/localize` package
into an appropriate bundle, where it will be executed before the renderer
needs to call `$localize`. For CLI based projects, this is best done in
the `polyfills.ts` file.
```ts
import '@angular/localize';
```
For non-CLI applications this could be added as a script to the index.html
file or another suitable script file.

Moving the tests over to CircleCI in pretty much "as-is" state just so that we can drop the dependency on Travis.
In the followup changes we plan to migrate these tests to run on sauce under bazel. @gregmagolan is working on that.
I've previously verified that all the tests executed in legacy-unit-tests-local already under bazel.
Therefore the legacy-unit-tests-local job is strictly not necessary any more, but given how flaky legacy-unit-tests-saucelabs is,
it is good to have the -local job just so that we can quickly determine if any failure is a flake or legit issue
(the bazel version of these tests could theoretically run in a slightly different way and fail or not fail in a different way, so having -lcoal job is just an extra safety check).

Allow passing an optional timeout to Testability's whenStable(). If
specified, if Angular is not stable before the timeout is hit, the
done callback will be invoked with a list of pending macrotasks.
Also, allows an optional update callback, which will be invoked whenever
the set of pending macrotasks changes. If this callback returns true,
the timeout will be cancelled and the done callback will not be invoked.
If the optional parameters are not passed, whenStable() will work
as it did before, whether or not the task tracking zone spec is
available.
This change also migrates the Testability unit tests off the deprecated
AsyncTestCompleter.
