and there is a weirdness with @RequestMapping in Spring 4.3

This reverts commit 8952cff2.

Adds an `@ExportMetricReader` which was missing before and
led to people losing their metric exports when they had Servo
on the classpath.

Also allow servo metrics autoconfiguration to be disabled via
a flag netflix.metrics.servo.enabled=false (as an alternative to
excluding the class in `@EnableAutoConfiguration`).

The zone for a remote server comes from its
eureka.instance.metadataMap.zone, but we didn't (until this change)
apply the same logic to the client. If the client is registering
itslef with eureka then it will have a metadataMap itself and
we should be able to just reverse the logic.
