* add Istio Gateway Source
* add documentation for Istio Gateway Source
* make both istio namespace and ingress gateway service configurable
* prefix gateway types, constructors, and flags with 'istio-'
* fix: add missing sources to source flag docs
When running in a pod sometimes the request to get ingreses/services
stalls indefinitely. A simple pod restart fixes this. Hard to reproduce
but I got lucky and did thread dump which revealed a gorouting blocked
on call to k8s.
What's new is a `--request-timeout` flag that makes requests to k8s
bounded in time. The default is 30s - this may cause some deployments
with a slow api-server to timeout.
* Add a flag that allows FQDN and Annotations to combine
Old behaviour is kept by default, a new flag is introduced to combine instead of overwrite
