* 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.
