Create a context span at ERROR level with skip_record enabled. This is intended to create spans whose only purpose it is to add context to child events; the span itself is never independently recorded.

Example:

use hyperactor_telemetry::context_span;

let span = context_span!("my_context", field1 = value1, field2 = value2);
let _guard = span.enter();
// ... do work that will be logged with this context
