http_endpoint Filebeat input to GA

[narph]

http_endpoint input is not yet GA although it has been around for while.

Checks to support GA:

• Integration tests exist system testing in beats and the http_endpoint integration testing in the integrations repo cover this
• System tests exist
• Documentation
• Fields follow ECS and naming conventions
• Implement e2e ACKs

Open issues

• Allow for local checkpoints once the new registry is available (optional)
