A61 says there will be a single Endpoint comprised of all the logical DNS addresses but we are still creating one endpoint for each address. |

No longer need to hard-code pick_first because of gRFC A61. grpc/proposal#477
Yes, that was a bug discovered in OutlierDetection (EnvoyServerProtoData). And yes, now XdsDepManager combines EAGs into a single endpoint.

grpc/proposal#477
This is still a WIP but I wanted to start the review as the remaining work is mostly tests at this point. (Yes, I there is one small TODO still in the main code.)This leaves ClusterResolverLb in-place. It'd be a follow-up to combine it with CdsLb. The tests include xdsDepManager instead of faking the XdsConfig object, which should make that PR easier, as well as many refactorings.
I'm almost to the logical dns tests, which will be the point
XdsDependencyManager.enableLogicalDnswill flip to true, as I can properly test it (and it is required).
