WebClient metrics support

[Delorien84]

It will be fine, to have metrics support for reactive org.springframework.web.reactive.function.client.WebClient. Currently there is support only for standard RestTemplate.

This depends on https://jira.spring.io/browse/SPR-16537. We currently don't have access to the parameterized URI to tag WebClient metrics with.

The upstream issue is resolved now, Is this still blocked?

[jkschneider]

Nope, no longer blocked, but won't be picked up until Boot 2.1 I'm guessing.

It's in 5.0.5, so maybe 2.0.1?
