* Remove unused extraClientSpans() method
* Merge extraAttributes() and hasClientSpanHttpAttributes(uri) into
httpAttributes(uri): this will allow to choose extracted attributes
per URI (for example, OkHttp won't set flavor on connection exception
once it's rewritten to Instrumenter)
* [WIP] Add peer.service to Instrumenter API
* Move PeerServiceAttributesExtractor to javaagent-api and use reflection to add it
* Finish PeerServiceAttributesExtractor
* Fix tests
* Add peer.service to apache-httpclient-5.0, jedis-1.4, lettuce-4.0
* Refactor TypeInstrumentation#transformers() method part 1
Add TypeInstrumentation and its implementations
* Refactor TypeInstrumentation#transformers() method part 2
Use the new method in all existing TypeInstrumentation implementations
* Drift
* Spotless

* Move and rename NetPeerUtils
* Rename NetPeerUtils to NetPeerAttributes; inject instance instead of using a global var
* Rename SpanAttributeSetter to AttributeSetter (might be used to set on AttributesBuilder in the future, who knows)
* Deprecate default BaseTracer constructor: library instrumentations are supposed to inject all dependencies, the javaagent should explicitly pass globals
* fix compilation failure
* Remove peer.service customization from library instrumentation
