Instead of a boolean, we now return a Status object. Status.OK
represents accepted addresses and other non-acceptance. This allows the
LB to provide more information about why a set of addresses were not
acceptable.
The status will later be sent to the name resolver as well to allow it
to also better react to to bad addresses.
FixedResultPicker can be used in more situations. Note that
WrrLocalityLoadBalancerTest's test was changed non-trivially. The
noChildLb test was particularly nasty as it assumed
LoadBalancer.ErrorPicker had same toString() as
GracefulSwitchLoadBalancer's ErrorPicker.
* Mark MultiChildLoadBalancer as Internal. Cannot move to the internal package because of its use of classes in the util package.
* Exclude MultiChildLoadBalancer from javadoc generation.
* Fix javadoc creation.
OutlierDetectionLoadBalancer did not delegate calls to an existing
ClientStreamTracer from the tracer it installed. This change has the OD
tracer delegate all calls to the underlying one.
