We were linting against usages of `fdescribe` and `fit` by referencing the `no-jasmine-focus` rule which isn't installed, causing tslint to log the following:
```
Could not find implementations for the following rules specified in the configuration:
no-jasmine-focus
Try upgrading TSLint and/or ensuring that you have all necessary custom rules installed.
If TSLint was recently upgraded, you may have old rules configured which need to be cleaned
```
These changes switch to using the built-in `ban` rule.

* No longer builds the example e2e tests using "tsc". The examples are now built with Bazel and can therefore be built with Ivy by using the `--define=compile=aot` switch.
* No longer runs the example e2e tests using the protractor CLI. example e2e tests are executed with the Bazel protractor rule and can therefore run incrementally.
NOTE: Unit tests found within the examples are still running within the legacy jobs.

This allows examples to be found during aio's `yarn serve-and-sync`, which only
looks for examples in `packages/examples/<packageName>/**/*`, where
`packageName` is the name of the package that the modified file belonged to;
e.g. `core`, `common`, etc.).
