migrate S3 notifications to ASF

[steffyP]

🚧 WIP 🚧

S3 bucket notifications for:

• SQS
• SNS
• Lambda (Cloudfunctions)
• Event Bridge

Implemented:

• s3_ObjectCreated_Put
• s3_ObjectCreated_Copy
• s3_ObjectCreated_CompleteMultipartUpload
• s3_ObjectRemoved_Delete
• s3_ObjectTagging_Put
• s3_ObjectTagging_Delete

Missing/Known Issues:

• [ ] s3_ObjectCreated_Post -> this is only triggered for pre-signed urls
• [x] test test_xray_header -> the required field is not set -> parsing headers from RequestContext only working for SNS now; no tests yet for lambda + SQS and not sure how it should work here
• [ ] validation for setting the configuration
• [ ] more tests (filters)
• [ ] missing notifications (we do not cover everything with tests)
