[Feature]: Create arbitrary log spans

[areibman]

💡 Feature Description and Proposed Solution

Langfuse has the functionality that lets users create log-style spans. They look something like this:

self.trace.event(name="xml_tool_call_limit_reached", level="DEFAULT", status_message=(
                                f"XML tool call limit reached - not yielding more content chunks"))

This is convenient for just showing where things might've gone wrong in a trace.

It would be great to have 2 functions:

• agentops.log(...)
• agentops.error(...)

I have create a TraceState enum in #1015 which has 3 StatusCode from OpenTelemetry mapped to strings.

I think having agentops.set_state(<state in str or agentops.<STATE>>) would be a better UX.
