Update all invocations to use the new context. The changes are all fairly simple, but there are a lot of them. Supporting minor changes: - Patch bump for all nodes that use the context - Update invocation processor to provide new context - Minor change to `EventServiceBase` to accept a node's ID instead of the dict version of a node - Minor change to `ModelManagerService` to support the new wrapped context - Fanagling of imports to avoid circular dependencies
