Metricbeat - GCP module - Pubsub - Ability to have topics labels

[naj-h]

Describe the enhancement: Add labels to the Metricbeat GCP module pubsub

Describe a specific use case for the enhancement or feature:

In GCP projects, one can have multiple topics and subscriptions which each serve a certain functional scope. One way to categorise them is to use labels. If metricbeat does not report labels, then one cannot use them to build specific visualisations by functional domain. Example below to give an idea :

This is a known issue. The GCP integration can only handle metadata of Compute services and Beats need to develop the proper workarounds on lightweight modules to extract the labels data.

The code to achieve this must be stored in the metrics Metricset. An example of how to do this can be found in the compute folder here https://github.com/elastic/beats/tree/main/x-pack/metricbeat/module/gcp/metrics/compute
