Rename grizzly-client instrumentation

Closes #1658

I think there is some confusion here.

https://github.com/AsyncHttpClient/async-http-client uses artifactId async-http-client and package name org.asynchttpclient
https://github.com/eclipse-ee4j/grizzly-ahc uses artifactId grizzly-http-client and package name com.ning.http.client.

The instrumentation under review monitors the second one, not the first one.

See my comment above

oh ya, com.ning.http.client was the package name prior to version 2.0, I've updated the README to note that we only support 1.9+ (not including 2.x yet)

Ok, I now understand better what is happening. But I am still not convinced this change is a good one. This instrumentation still was written for https://github.com/eclipse-ee4j/grizzly-ahc, judging from package and artifact names. Why do we want to instead say that this is about old version of https://github.com/AsyncHttpClient/async-http-client? Then we should change gradle build file and test with those artifacts, whose artifactId=async-http-client-project
