The return value of `listSchematicNames` will include hidden schematics when is invoked with true as first parameter.
By default, hidden schematics are not returned.
This change first attempts to resolve a schematic referenced via the external schematic rule from the requesting schematic collection. This allows schematic packages that are direct dependencies of another schematic package to be used with the external schematic rule without manual package resolution code within the schematic.

This allows a rule to conditionally not return a followup rule when asynchronous. This is useful to handle error conditions where no further action should be taken and returning void best expresses this case.
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.
Schematics context now have an (optional) analytics field that, if set,
should be used to report usage. This can be set even in some cases where
analytics is disabled (to a noop analytics).
Currently, all third-party schematic developers are forced to use and directly depend on `rxjs` if any logic is asynchronous. Doing so can can also add overhead and unneeded complexity for organizations that have chosen to standardize on async/await usage. This change allows such parties to rely on native promise support if desired.
And receives in its constructor the enginehost and registry. This simplifies the creation
of the NodeWorkflow, or later on the Google3Workflow etc, since all the duplicate logic
is now in a single base class.
This is yak shaving for internal stuff.
