The shared test is "lifted" from existing "native" (Apache HttpClient)
tests, and it is strictly blocking, so assertions happens that body is not
touched, while new clients do some things "ahead" to optimize, so still remains
how to settle these (IMHO minor) differences, but to not loose any notable
information. All 3 new transport UT passes when these fine grained assertions
are removed.

> Issue Type: Task
> Components: Resolver
> Reporter: Tamas Cservenak
> Priority: Major

> For HTTP protocol resolver currently provides following transports:
> * transport-wagon that uses Maven 2.x Wagon, that among other protocols
> supports HTTP/1.1 as well
> * transport-http that uses directly Apache HttpClient 4.x supporting
> HTTP/1.1 but provides enhancements in form of "checksum strategy" (almost all
> of remote repositories emit those in headers, sparing one HTTP round-trip)
> As we saw, is very easy to outperform these as:
> * Maven Central supports HTTP/1.1 but also HTTP/2
> * HTTP/3 is on the way as well
> An experiment involving Jetty Client far outperformed both of existing
> transports, most probably due HTTP/2 support.
> So, clients we should consider:
> * Jetty Client
> * OkHTTP
> * Java 11 HttpClient
> Point is, to invest into something that (ideally) transparently supports
> HTTP/1.1 and HTTP/2, and more ideal would be if even HTTP/3 would be
> transparently supported (Jetty 12 works on that). We could then simply
> compare these implementations, count in pros and cons, and decide where we
> want to go,
