Description

After upgrading Jetty version to 9.4.32.v20200930 the suite BasicHttpSolrClientTest started to fail because of how the compression/decompression is handled on the client side.

Jetty changed its behaviour with this upgrade as part of the so for empty responses (Content-Length: 0) with Accept-Encoding: gzip it's still returning a Content-Encoding: gzip but with no gzip header bytes in the response.

Jetty's relevant issue: https://github.com/eclipse/jetty.project/issues/4824
Jetty's relevant code changes: https://github.com/eclipse/jetty.project/commit/d58da0f7d2e30c732f52a38feaba2974e299bf70#diff-e175032f6f83c7d41fb7bc1a66187f5aR232

Interceptors should be removed and BasicHttpSolrClient should use Apache HttpClient's provided processors decompress the HTTP responses.
