Edge functions: regional invocation with an array of allowed regions

Currently one region can be selected with x-region for regional invocation. However, I could not confirm if there is re-routing or not if selected region has an outage. I submitted a bug report for this. This might create compliance issues if request re-routes to an unwanted region. Also, even if the feature is working correctly, being able to select only one region might create service interruptions to the user when the selected region is down or might experience latency. If there is an allowed list, it can solve this issue. Proposed request with a new header 'x-allowed-regions' :

curl --request POST ' \
--header 'Authorization: Bearer ANON_KEY' \
--header 'Content-Type: application/json' \
--header 'x-allowed-regions: ["eu-central-1", "eu-west-1", "eu-west-2", "eu-west-3"]' \
--data '{ "name":"Functions" }'
