Add new Logpush fields for max upload params

[Evesy]

Description

Adds new Logpush fields as documented here https://developers.cloudflare.com/logs/get-started/api-configuration/#max-upload-parameters

• max_upload_bytes
• max_upload_records
• max_upload_interval_seconds

The new fields do have server side validation around the integer values, I wasn't sure whether this client should perform the same validation. Opted out for now as I assume the client doesn't want to be tied into values that could easily change in Cloudflares API.
Similarly, max_upload_bytes and max_upload_records cannot be used if kind is set to edge, not sure if that's validation that should be done in the client or not?
