Add checkbox for cleaning up operand when uninstalling operator

OLM is adding a property to the CSV to signal that the operator should clean up the operand on operator uninstall. See https://github.com/operator-framework/enhancements/pull/46

Console will need to add a checkbox to the UI to prompt ask the user if the operand should be cleaned up (with strong warnings about what this means). On delete, console should set the `spec.cleanup` property on the CSV to indicate whether cleanup should happen.

Additionally, console needs to be able to show proper status for CSVs that are terminating in the UI so it's clear the operator is being deleted and cleanup is in progress. If there are errors with cleanup, those should be surfaced back through the UI.

Depends on OLM-1733
