Include Rate Limit status data in query result output

[Ted van der Veen]

When querying the GitHub v4 GraphQL endpoint, the response contains HTTP headers that indicate the current Rate Limit status:

X-RateLimit-Limit: 5000
X-RateLimit-Remaining: 4999
X-RateLimit-Reset: 1576224622

This information is currently ignored, but I need it to pro-actively avoid running into 429 responses and have my toolset take a break before sending the next request.

Maybe the most simple solution is to use the great Polly library and setup a WaitAndRetryAsync retry policy that handles 429 responses from the Github API and respects the X-RateLimit-Reset HTTP header?
