[jdk17u-dev] RFR: 8305906: HttpClient may use incorrect key when finding pooled HTTP/2 connection for IPv6 address [v2]

[Jaikiran Pai]

> Can I please get a review for this change which backports the fix that was done in https://bugs.openjdk.org/browse/JDK-8305906?
> 
> The fix in the source is a clean backport. However, the newly introduced test in mainline uses a test specific libraries which aren't the same in 17u. As a result, the tests `test/jdk/java/net/httpclient/http2/ConnectionReuseTest.java` had conflicts. I have manually updated relevant parts of that test to make it use the test libraries that are available and applicable in 17u. 
> 
> I have also verified that the test fails (as expected) if I undo the source change and passes when I re-introduce the source change. Additionally, I have run this test in our CI to verify that it passes.
