Memory leak with unclosed span in opentelemetry integration

[vanchaxy]

How do you use Sentry?

Sentry Saas (sentry.io)

Version

1.40.3

Steps to Reproduce

SentrySpanProcessor stores all open span in self.otel_span_map dict. This leads to a memory leak if otel span is deleted without closing. E.g. due to a bug: open-telemetry/opentelemetry-python-contrib#2149

Expected Result

Sentry span should be deleted after otel span is deleted by GC.

Actual Result

Sentry spans are stored in self.otel_span_map forever.

Thanks for the report @vanchaxy, putting this in our backlog.

Same problem, docker containing the flask process crashes about once an hour due to memory overflow when no heavy tasks are performed.
