[DO NOT MERGE] feat: add Beat processor

[andrzej-stencel]

Shows how Beat processor can be used in Elastic Agent.

I have replaced the Beats dependency in go.mod with:

go mod edit -replace=github.com/elastic/beats/v7=github.com/andrzej-stencel/beats/v7@add-beat-processor
go mod tidy

See https://github.com/andrzej-stencel/beats/tree/add-beat-processor.
