child_process.spawn() with `shell: true` does not quote its arguments, so any data passed in must be surrounded by quotes to properly include spaces. This was making tests fail when the repository is checked out to a directory with a space in it.
Easiest solution is to simply not use shell escaping which avoids the whole problem.
This should be reintroduced in 9.1 or 9.2. The other remaining "hidden" peer dependencies should be included as well (currently `karma` and `node-sass`).
At the moment we are relying on source content to determine if the compilation is under Ivy or VE. However, we do know what compilation we are in from the parsed tsconfig.
With this change we use the `enableIvy` to set the analytics metric

BREAKING CHANGE:
Removed several deprecated APIs:
- EngineHost `listSchematics` has been removed in favour of `listSchematicNames`.
- `FileSystemSink` - Use the new virtualFs.Host classes from `@angular-devkit/core`.
- `optimize` function has been remove as trees are automaticlly optimized.
- `DryRunSink` deprecated constructor that allowed to provide a directory path has been removed. Provide a `virtualFs.Host` instead.
