* [devUtils/toolingLog] give tooling log configurable writers
* property shorthand
* remove redundant parameter
* call Error.captureStackTrace when subclassing Error
* describe why we skip stack trace logging for CliError
* always return true/false from log writers
* improve type definitions, writeTo is just an object with write method
* get rid of weird dedent for failures
This PR upgrades RxJS to version 6 and switches to a fork of `stream-to-observable` which includes an updated version of `any-observable` that supports RxJS 6 until https://github.com/jamestalmage/stream-to-observable/pull/10 is merged. The primary change in this version of RxJS is the movement of stream operators from `Obersable.prototype` to the `rxjs/operators` module. Some of the operators, like `catch` and `do`, have been renamed (`catchError`, and `tap`). The Obsevable factories have also been moved from static methods on the `Observable` class to named exports of the root `rxjs` module. Some of those factories have also changed slightly, like `fromEvent` which now emits arrays if the event handler is called with multiple arguments.
```js
// import the Rx namespace to get the Observable factories
import * as Rx from 'rxjs';
// import the operators as named imports
import { map, tap, switchMap } from 'rxjs/operators';
```
* [tslint] lint typescript code
* [tslint] filter projects when running specific project
* [dev/ts] use more explicit types
* [dev/ts] add note about why using glob
* [dev/ts] rely on ts, use fewer getters
