Index more sqlite cache fields (#271)

* Add more fields to index when sql-caching is on.

Misc changes:
- Use the builtin Event class, not events.k8s.io (by looking at the dashboard client code)
- Specify full path to the management.cattle.io fields.
- Map `Event.type` to `Event._type` for indexing.

Use a compound transform-func to first check for a "signal",
and then to run all the relevant transformers until either
one fails or the list is exhausted.

- Includes moving the fakeSummaryCache type into a common area.

Use a simpler way of running transforms.

* Inline the function to get the gvk key.

* Create a '--sql-cache' flag to turn on caching for the steve CLI.

* Improve error-handling in object transformer.

* Drop the 'GetTransform' function.

* Inline the code that transforms a payload into a k8s-unstructured object.
