Just 3 comments, but the rest looks good to me. I no longer see us reading the whole payload like before, is that right? Now we just unmarshal, the armor log struct is part of load balancing

LGTM! I didn't look through all the code, mostly focused on the mappings.

This can be considered a breaking change, as some log types will be parsed differently due to additional support. However, we have not gone live with an official release, so the major version will not be bumped. See below for OpenTelemetry Collector-related log parsing changes: - https://github.com/open-telemetry/opentelemetry-collector-contrib/releases/tag/v0.142.0 - extension/googlecloudlogentry_encoding: Parse External Application Load Balancer logs into log record attributes instead of placing it in the body as is. (open-telemetry/opentelemetry-collector-contrib#44438) - extension/googlecloudlogentry_encoding: Add support for GCP VPC Flow Log fields for MIG (Managed Instance Group) and Google Service logs. (open-telemetry/opentelemetry-collector-contrib#44220) Adds support for the following GCP VPC Flow Log fields: - https://github.com/open-telemetry/opentelemetry-collector-contrib/releases/tag/v0.143.0 - extension/googlecloudlogentry_encoding: Parse Cloud DNS Query logs into log record attributes instead of placing it in the body as is. (open-telemetry/opentelemetry-collector-contrib#44561) - extension/googlecloudlogentry_encoding: Add support for Passthrough External and Internal Network Load Balancer logs (open-telemetry/opentelemetry-collector-contrib#44524)

Description
This PR adds support for parsing both types of GCP Application Load Balancers (regional and global).
With this changes, the user will be able to see load balancer logs reported information in log attributes instead of pasted as a raw json string into the log body, that could cause the user to overlook important info.
Also modified armor log parsing to allow parse more than one policy types included in a single log entry.
