Centralize the creation of the dialer during startup.
Have the dialer then passed in to both APIServer and Aggregator.
Aggregator the sets the dialer on its Transport base.
This should allow the SSTunnel to be used but also allow the Aggregation
Auth to work with it.
Depending on Environment InsecureSkipTLSVerify *may* need to be set to
true.
Fixed as few tests to call CreateDialer as part of start-up.
proxy_handler now uses the endpoint router to map the cluster IP to
appropriate endpoint (Pod) IP for the given resource.
Added code to allow aggregator routing to be optional.
Updated bazel build.
Fixes to cover JLiggit comments.
Added util ResourceLocation method based on Listers.
Fixed issues from verification steps.
Updated to add an interface to obfuscate some of the routing logic.
Collapsed cluster IP resolution in to the aggregator routing
implementation.
Added 2 simple unit tests for ResolveEndpoint
