Protocol: Send envelope types with requests

[mwarkentin]

Description

We currently have no visibility into the type of event that we are dealing with in any of our systems before we hit relay. These are mainly the Google load balancer and our anti-abuse PoP layers.

An example of this issue came up in INC-648, where there are submitted events receiving errors from the GLB and never making their way to our backend systems. It's difficult to understand what type of events are running into these issues.

questions

• is this a new http header?
• i assume we just take the first item type if the envelope has multiple items

is this a new http header?

We can also send as a query param, this feels like an implementation detail so I edited the issue accordingly.

i assume we just take the first item type if the envelope has multiple items

Yup first envelope item seems safest to send
