* https://github.com/kubernetes/ingress-nginx/issues/3070
* https://github.com/kubernetes/ingress-nginx/issues/3335
* add a 503 test
* test a service that starts out empty
(a.k.a. ingress-nginx controller (re-)start)
* test scaling up (should route traffic accordingly)
* test scaling down to empty service
* use custom deployments for scaling test.
* provide a fix by updating the lua table (cache) of the configured backends
to unset the backend if there are no endpoints available.
Actually read from the file
Logs probably shouldn't assume knowledge of implementation detail
Typos
Added integration test, and dynamic update config refactor
Don't force the 8k default
Minimal test case to make the configuration/backends request body write to temp file
Leverage new safe config updating methods, and use 2 replicas instead of 4
Small refactor
Better integration test, addresses other feedback
Update bindata
* e2e tests for dynamic configuration and Lua features
* do not rely on force reload to dynamically configure when reload is needed
* fix misspelling
* skip dynamic configuration in the first template rendering
* dont error on first sync
