Migration to Angular 6, RxJs 6 and Webpack 4 (#2019)

* AoT and JIT builds complete successfully

* Upgraded @ngtools/webpack to latest beta.

* Fixed warnings, removed deprecated plugins, replaced npm run clean:dist and clean:aot with direct rimraf calls to speed up the script execution

* Govinda Alwani : Upgraded HtmlElementsPlugin to support webpack 4.

* Updateing angular 6 and ficing webpack issues and rxjs issue.

* using RXJS lettable

* Update README.md

* Updating Angular latest and webpack latest

* Updated lock file

* Corrected package-lock.json

* Got rid of outdated ngcWebpackPlugin. Instead using native AngularCompilerPlugin directly.

* Added RxJs TSLint rules

* Clean-up, refactoring, re-enabled disabled TSLint rules

* Partially reverting previous change as it causes one of e2e tests to fail for no apparent reason... Have to be investigated.
