moving to cxf-rt-transports-http-hc5
The master branch is on CXF 4.1.0 and Spring Boot 3.3.7, but the former depends on Apache Commons HttpClient 5.4.1 while the latter brings Apache Commons HttpClient 5.3.1.
CXF 4.0.6, depends on HttpClient 5.31, Spring Boot 3.4 is bringing HttpClient 5.4.1.
So we should either postpone the move to cxf-rt-transports-http-hc5 once the codebase is upgraded to Spring Boot 3.4, or downgrade CXF to 4.0.6.
The current test errors might be fixed by https://github.com/apache/cxf/pull/2202 once merged
I've backported https://github.com/apache/cxf/pull/2202 to CXF branch 4.1.x-fixes, built locally and updated this PR to use CXF 4.0.7-SNAPSHOT, but the errors remain unchanged.
