Configuring GCP credentials

In order to make the Wazuh GCP module pull log data from Google Pub/Sub, it will be necessary to provide access credentials so it can connect to them.

To do this, we will need to create a service account with the Pub/Sub permissions and then create a key. It is important to save this key as a JSON file. We will use this file as credentials for the GCP module.

Your key should have this format:

{
   "type": "service_account",
   "project_id": "wazuh-gcloud-258815",
   "private_key_id": "1f7578bcd3e41b54febdac907f9dea7b5d1ce352",
