Description

iiuc hitting the web ui for non-leading schedulers redirects to the leader. this doesn't really help the members of the ensemble are not publicly routable.

if there was a /leader endpoint that returned "200 OK" if it is leader and some 3xx/4xx code if not, then it would be easier to configure an ELB to route traffic to the correct leader, simplifying the use of aurora in an AWS deployment.
