Description

DRAFT: Needs go and python support to be implemented.

This PR enables parse_multiline for OTel. It requires GoogleCloudPlatform/opentelemetry-operations-collector#405 to be merged for access to the recombine operator.

This also fixes our OTel support to preserve leading and trailing whitespace on log lines, which makes it match fluent-bit's behavior better. This causes (correct) changes in existing transformation test output.
