Investigate disable event normalization processing in Cloudfoundry input

In this issue we will evaluate the benefits in cpu utilisation of filebeat cloud foundry input if we disable event normalization to reduce allocations when processing events.
This was made possible due to [this PR](https://github.com/elastic/beats/pull/33657).

The tests are performed with latest Elasticsearch 8.6 deployed on Elastic Cloud.
The https://apps.sys.giz-2.cf-obs.elastic.dev PCF cluster will be used and traffic will be generated using a log-generator app, each instance of which generates 100K events per minute.
There will be a comparison of cpu usage between a filebeat that disables event normalization and the default filebeat.
