How to test this PR locally

On each our elastic-agents wie configured some variables to identify our systems in the local elastic-agent.yml:

providers:
  local:
    vars:
      acme_serverid: '12345678-abcd-1234-5678-abcdefgh1234'
      acme_systemid: '87654321-b769-04d5-c851-e8bb5044fb4e'

In the integration settings we consume these variables by following processors:

And we can now see our custom ids in the stream to be able to use these for mappings to the rest of our managment tools.
