[FEATURE]: make X-Super-Client header required

[dealloc]

What problem does it solve

It requires clients using the hosted version of the API to send along a X-Super-Client header that identifies their application, and optionally a X-Super-Contact header with developer contact info.

This allows us to identify applications and contact developers when implementing breaking changes or if their apps are causing problems.

What is the solution

Make the header required (after a grace period)

Existing alternatives

none

Added value

This allows us to identify applications and contact developers when implementing breaking changes or if their apps are causing problems.

Additional notes

Provide a way to disable this check for self-hosted containers

What kind of grace period are we looking at for mandatory implementation?

[dealloc]

mostly depends on how fast I can identify most developers and communicate the changes

We left the Elixir version up and running for approximately 30-50 days
