Description

Currently the HotROD trace from microsim looks like this:

In contrast, the real trace only has errors in the Redis call leaves, but the parent requests are not marked as errored, because the Redis errors are considered non-fatal.

microsim should have an option to not bubble up child errors to the parent.

Contributor guide

Research direction
Investigate how child errors are currently propagated to parent spans in the microsim codebase. Look for error handling in span creation and closure. Implement an option to mark child errors as non fatal, preventing them from marking parent spans as errored.
