agent: observability

When does this happen?

IF When using phoenix-otel v0.10.0 and calling register() with verbose=True, an UnboundLocalError is thrown because the span_processor variable is not defined when multiple span processors exist.

How others solved it

THEN Upgrade phoenix-otel to v0.10.1 or later, or set verbose=False in the register() call to avoid the crash.

pip install --upgrade arize-phoenix-otel>=0.10.1
